ZXR10 Command Manual (MPLS Volume) clear mpls ldp Use this command to reset the LDP router or its connection with some neighbor. Privileged EXEC clear mpls ldp [neighbor <ip-address>] neighbor <ip-addre ss> IP address of the neighbor, in the dotted decimal format Instructions After this command is configured, the router is reset and interrupted, and all LDP sessions are reestablished. The recheck of the access-fec and egress policies, advertisement and request policies, and the explicit pop-up label advertisement policy is performed on all FECS. The resetting of the session with the designated neighbor means the interruption and the reestablishment of the LDP session with this neighbor only. The recheck is only performed on the policy related with this neighbor (advertisement, request, and exp-null policies). This example describes how to reset LDP. ZXR10#clear mpls ldp This example describes how to reset the session with the LSR whose router ID is 100.1.1.1. ZXR10#clear mpls ldp neighbor 100.1.1.1 clear mpls ldp dampening Use this command to clear LDP routes dampening and unsuppress the suppressed routes. Privileged EXEC clear mpls ldp dampening [<ip-address><net-mask>] <ip-address> The network IP address relates to clear damp information, in the dotted decimal notation <net-mask> Network mask, in the dotted decimal notation Instructions After this command is configured, the router will clear and reset LDP dampening information already generated, and the router will unsuppress the suppressed LSP; the router will reset flapping suppress information of some specified LSP, and only the dampening information of this LSP will be cleared. If this LSP is suppressed, the router will unsuppress it. This example describes how to reset LDP dampening information. ZXR10#clear mpls ldp dampening 8 Confidential and Proprietary Information of ZTE CORPORATION
Chapter 2 MPLS LDP Configuration This example describes how to reset dampening information of a LSP. ZXR10#clear mpls ldp dampening clear mpls ldp flap Use this command to clear the flapping statistic information of LDP routers. Privileged EXEC clear mpls ldp flap [<ip-address><net-mask>] <ip-address> Network IP address, in the dotted decimal format <net-mask> Network mask, in the dotted decimal format Instructions After this command is configured, the router will clear the count of the flapping of LDP entities where flapping has already occurred, and the router will reset the count of the flapping of some specified LSP; only the count of the flapping of this LSP is cleared and reset and it will be recounted from 0. This example describes how to rest LDP flapping statistic information. ZXR10#clear mpls ldp flap This example describes how to reset the flapping statistic information of a LSP. ZXR10#clear mpls ldp flap 100.1.1.1 32 mpls ip (Global Configuration) Use this command to enable LDP to establish an LSP along a common hop-by-hop routing path. Disable LDP with the no form of this command. Global configuration mpls ip no mpls ip LDP is disabled by default. Instructions his command enables LDP to establish an LSP along a common hop-by-hop routing path. In addition, it is necessary to enable LDP on the interface to realize dynamic label switching on the interface. Confidential and Proprietary Information of ZTE CORPORATION 9
ZXR10 Command Manual (MPLS Volume) Use the no form of this command to disable LDP to establish an LSP along a common hop-by-hop routing path no matter whether LDP is enabled on the interface or not. mpls ip(interface Configuration) Use this command to enable LDP label switching on the interface. Disable LDP label switching with the no form of this command. Interface configuration mpls ip no mpls ip This command is disabled by default. Instructions This command enables LDP to exchange labels on the interface of layer 3. Once the command is configured, LSR starts to periodically send hello messages on the interface. When packets to the destination network obtain the outgoing label to some destination network, the outgoing label will be added into the packets and the packets will be forwarded from this interface. Note that this command will take effect only after mpls ip is configured in global configuration mode. Related Commands The no form of this command make packets routed from this interface no more carry labels and cease the label switching on the interface. This example describes how to enable LDP on the interface fei_1/1. ZXR10(config)#mpls ip ZXR10(config)#interface fei_1/1 ZXR10(config-if)#mpls ip show mpls interface show mpls ldp discovery mpls label range Use this command to configure a label range for LDP. Restore default with the no form of this command. Global configuration mpls label range <min-label><max-label> no mpls label range <min-label> Minimal available label, range: 16~1048575 <max-label> Maximal available label, range: 16~1048575 10 Confidential and Proprietary Information of ZTE CORPORATION
Chapter 2 MPLS LDP Configuration This example describes how to set the label range as 1000~10000. Related Commands ZXR10(config)#mpls label range 1000 10000 show mpls label range mpls ldp access-fec Use this command to control LDP s creation of FEC for which destination networks and make sure whether FEC can be created for routing networks obtained by BGP; this command controls FEC filter policy. To disable this feature, use the no form of this command. Global configuration mpls ldp access-fec {for <prefix-access-list> host-route-o nly bgp force} no mpls ldp access-fec [bgp] for <prefix-access-li st> Destination network to be filtered, basic ACL: 1~99 and 1000~1499 host-route-only bgp force Creates FEC only for the destination network (host address) with 32-bit mask Creates FEC for the specified route network obtained from BGP Takes effect immediatedly LDP creates FEC for all destination networks except the route networks obtained by BGP. Instructions By default, LDP creates FEC for all destination networks except the route networks obtained by BGP. However, the number of networks may be so large that it needs to filter the network for which FEC need not be created ; or the network administrator wants to control the creation of FEC, that is, FEC is created only for the authorized network. This command can realize such functions. The mpls ldp access-fec for <prefix-access-list> command can make filter be based on access list. FEC can be created for all destination addresses allowed by the access list. Only standard ACL is supported now. The mpls ldp access-fec host-route-only command make FEC be created only for the destination address with 32-bit mask. The mpls ldp access-fec host-route-only command is especially valid in the MPLS/BGP VPN application, because under such application, LDP only exchanges the label of the next-hop address (that is, the outer label, the label to the PE) of VPN routes. The mpls ldp access-fec host-route-only command can effectively decrease the number of FECs. This command does not collide with the above two policies. By default, FEC is not created for route networks obtained by Confidential and Proprietary Information of ZTE CORPORATION 11
ZXR10 Command Manual (MPLS Volume) BGP. This command can make FEC also be created for route networks obtained by BGP. Use the mpls ldp access-fec command to configure policy but it does not take effect immediately. But The mpls ldp acce ss-fec force command makes the configuration take effect immediately. Tip: mpls ldp access-fec for <prefix-access-list> and mpls ldp acce ss-fec host-route-only are mutually exclusive. Thus the network administrator can choose only one control policy at any time. 1. This example describes how to configure the router to create FEC only for the destination address with 32-bit mask: Related Commands ZXR10(config)#mpls ldp access-fec host-route-only 2. This example describes how to configure the router to create the labels of networks 10.101.0.0 and 10.221.0.0 only and they act immediately. ZXR10(config)#ip access-list standard 10 ZXR10(config-std-nacl)#permit 10.101.0.0 0.0.255.255 ZXR10(config-std-nacl)#permit 10.221.0.0 0.0.255.255 ZXR10(config-std-nacl)#exit ZXR10(config)#mpls ldp access-fec for 10 3. This example describes how to configure the router to create FEC for route networks obtained by BGP. ZXR10(config)#mpls ldp access-fec bgp show mpls ldp binding show running-config mpls ldp advertise-labels Use this command to control the distribution of locally assigned labels (incoming labels) through LDP. This command controls which destination network segment labels are advertised to which neighbors. To disable this feature, use the no form of this command. Global configuration mpls ldp advertise-labels [for <prefix-access-list>[to <peer-a ccess-list>]] no mpls ldp advertise-labels [for <prefix-access-list>[to <pee r-access-list>]] for <prefix-access-li st> Destination network label to be advertised, basic ACL: 1~99 and 1000~1499 to <peer-access-list> Advertises which labels to which neighbors, basic ACL: 1~99 and 1000~1499 12 Confidential and Proprietary Information of ZTE CORPORATION
Chapter 2 MPLS LDP Configuration Instructions All labels are advertised to all neighbors by default. The no mpls ldp advertise-labels command without any optional parameter forbids the distribution of any locally assigned labels. To restore the distribution of all locally assigned labels, use the mpls ldp advertise-labels command without any optional parameter. Only standard ACL is supported now. Up to 99 mpls ldp advertise-labels commands can be executed, those commands work together to determine how LSR advertises local labels. In the case that multiple commands are configured, the following rules should be followed: 1. Each mpls ldp advertise-labels command has a (prefix acl, peer acl) pair. The access list pair is (none, none) when no optional parameter is specified; and it is (prefix-acl, none) when the optional parameter is specified but without the keyword no. 2. There is only one (prefix acl, peer acl) pair applied to each prefix in accordance with the following rules: i. One (prefix acl, peer acl) pair applies to one prefix only when prefix acl matches the prefix, and the match condition is that prefix acl permits the prefix. ii. In the case that there is more than one (prefix acl, peer acl) pair matching a prefix; the first (prefix acl, peer acl) pair applies to the prefix (in the sequence configured in show running-config). 3. When LSR is to advertise a prefix label, it executes the following operations: i. Finds the (prefix acl, peer acl) pair applied to the prefix. ii. In the case that there is no (prefix acl, peer acl) pair applied to the prefix, the label is not advertised to any neighbor if the no mpls ldp advertise-labels command is executed; otherwise, the label is advertised to all neighbors. iii. In the case that one (prefix acl, peer acl) pair applied to the prefix, the label is not advertised to any neighbor if prefix acl denies the prefix. iv. If prefix acl permits the prefix and there is no peer acl (namely none), the label is advertised to all neighbors. v. If prefix acl permits the prefix and there is one peer acl, the label is advertised to all neighbors permitted by peer acl. Tip: This command takes effect immediately after its configuration. The command can be configured only when the network in stable status. Otherwidse, it could not take effect immediately. Do not use this command frequently. 1. This example describes how to forbid the router from advertising any label to any neighbor. ZXR10(config)#no mpls ldp advertise-labels Confidential and Proprietary Information of ZTE CORPORATION 13

This is the general processing method of access list. In the early Cisco IOS version, however, the parameter <prefix-ac cess-list> after the keyword for in the mpls ldp advertise-labels command is interpreted in a different way as follows: One (prefix acl, peer acl) pair applies to a prefix only when the prefix ACL matches the prefix, and the match condition is that 14 Confidential and Proprietary Information of ZTE CORPORATION

ZXR10 Command Manual (MPLS Volume) interface <ip-address> Specifies the interface address as the transmission address advertised in the hello message Specifies some address as the transmission address advertised in the hello message Instructions By default, ZXR10 takes the router identifier as the transmission address advertised in the hello message on the frame interface. A TCP connection must be established before an LDP session is set up between LDP routers, which requires every router know the peer transmission address (IP address). The LDP discovery mechanism enables the LDP router to advertise its own transmission address used for establishing TCP connection to the peer. The advertisement of the transmission address can be explicit (that is, the transmission address appears in the hello message) or implicit (that is, there is no transmission address appearing in the hello message). The receiver of hello messages takes the source IP address of the hello message as the transmission address to set up TCP connection with the sender. The mpls ldp discovery transport-address command provides a way to change the default behavior of the router. If the interface parameter is used, LDP advertises the IP address of the interface in the hello message on the interface. If the <ip-address> parameter is used, the LDP advertises the designated IP address in the hello message on the interface. If the configuration of the transmission address is changed during the precess of the running of the interface, ZXR10 router will delete the current adjacency relationship on the interface. If there is no other adjacent relationship maintaining the session maintained by the current adjacent relationship on the interface (multiple links do not exist), the session will be closed. The adjacency relationship (and the session) will be reestablished after a hello message is received from the peer. Tip: If there are multiple links between routers, these routers must advertise the same transmission address on the corresponding interfaces.

By default, LDP allocates popup labels only to the directly connected networks and makes advertisements to the peer LSR. For destination networks not directly connected, LDP acquires the idle label from the label pool as the incoming label and chooses the label value in the mapping message sent by the next hop of the route as the outgoing label. If local router is an edge LSR and the router of nexthop may be a non-mpls router, local LSR cannot bind the outgoing label, and the received label packet be will discarded at the data layer because there is no outgoing label according to the MPLS framework protocol. In this case, it is necessary to configure the egress control policy to specify LDP to allocate popup labels to destination networks flowing out of MPLS network, and make advertises to the upstream LSR. Thus upstream LSR will forward the traffic from the MPLS network in the form of IP packets (or explicitly popup label packets). There are two kinds of control policies: based on destination network segment and based on next hop. 1. The egress control policy based on destination networks (mpls ldp egress for <prefix-access-list>) directly specifies which destination where local LSR is terminated. 2. The egress control policy based on next hop (mpls ldp egress nexthop <nexthop-access-list>) specifies which neighbors are non-mpls routers so that the traffic of these neighbors as next hops is the traffic out of MPLS. Local router allocates popup labels for this traffic. As long as a route meets either of the two policies, that is, the destination prefix is permitted by <prefix-access-list> or the next hop is permitted by <nexthop-access-list>, the LDP will allocate a popup label to it. The policy takes effect only on the refreshed FECs after the configuration and does not reallocate labels to the existing FECs. There- Confidential and Proprietary Information of ZTE CORPORATION 21

Instructions By default, ZXR10 advertises directly connected networks to all neighbors by means of implicit null labels. The implicit null label causes the Penultimate Hop Poping (PHP) router to make PHP. Sometimes, however, it is prohibited for the PHP router to make such action so that the explicit null label is used in the outgoing label forwarding packet. The mpls ldp explicit-null command enables the router to advertise explicit null labels to the neighbors permitted by<pe er-access-list> and the directly connected networks permitted by <prefix-access-list>. If the parameter <prefix-access-list> is not specified in the command, explicit null labels will be advertised to all the directly connected networks; if the parameter <peer-access-list> is not specified in the command, explicit null labels will be advertised to all neighbors. This command takes effect only to the label advertisement messages after the configuration. If labels have been advertised before the policy is configured, and the matched networks and neighbors will not change unless the session is interrupted and reestablished.

Secondly, if there are loopback interfaces configured with IP addresses, the maximum IP address of the loopback interface will serve as the router identifier. 3. Lastly, among the IP addresses of interfaces configured with IP addresses and in the UP state, the maximum one is selected as the router identifier. By default, the automatically elected router identifier may be unavailable sometimes, for example, the routing protocol does not advertise the IP address elected as the router identifier to neighbors. In addition, the router configuration may cause the LPD router identifier is uncertain, and this invalidates the neighbor s control policy. 26 Confidential and Proprietary Information of ZTE CORPORATION
Chapter 2 MPLS LDP Configuration Related commands The mpls ldp router-id command specifies the IP address of an interface as the router identifier. Note that the interface whose IP address serves as the router identifier must be in the UP state. If the optional parameter force is not specified, the router identifier specified by the mpls ldp router-id command will not take effect until the next router identifier election, and the router identifier takes place in the following cases: 1. LDP restarts. 2. The interface whose IP address serves as the current router ID is shut down. 3. The interface whose IP address is specified as the current router ID is not configured with any address. If the optional parameter force is specified, the effect of the m pls ldp router-id command depends on the current state of the specified interface. 1. If the specified interface is in the UP state and its address is not the current router identifier, the router will change the router identifier to the specified value, interrupt all the current sessions, release labels learned from the sessions, and terminate the MPLS forwarding related with the bounding of these labels. 2. If the specified interface is in the DOWN state, the router will change the router identifier to the specified value once the interface is in the UP state, interrupt all the current sessions, release labels learned from the sessions, and terminate the MPLS forwarding related with the bounding of these labels.

This command is supported to be configured under vfi mspw configuration mode after the platform version 4.8.20. The current solution does not support the VPLS automatic discovery mechanism, thus it is necessary to specify all PE addresses in the same VPLS.

Use this command to specify the type of a pseudo-wire in a static multi-hop pseudo-wire S-PE configuration instance. VFI configuration or VFI MSPW configuration pwtype {ethernet ethernet-vlan} ethernet ethernet-vlan Pseudo-wire type: Ethernet or Ethernet-vlan Instructions This command is supported after the platform version 4.6.02. When a pseudo-wire is established between two PEs, there must be the negotiation about the type of the pseudo-wire established. There are two types of the pseudo-wire in VPLS: Ethernet and Ethernet-vlan. The establishment of a pseudo-wire will fail if the pseudo-wire types designated by PEs are different. The two pseudo-wire types correspond to two ways for providing the VPLS service. If the pseudo-wire type is Ethernet, the VPLS service is provided in the transparent mode. That is, the PE directly forwards the user data without checking or processing the vlan tag of the user data. In this case, the the vlan tag is regarded as the distinguisher for the user to manage private networks. In this mode, the input interface offered to the user must be the real interface. If the pw type is Ethernet-vlan, the VPLS service is provided in the rewrite mode. That is, the ingress PE router peels off the vlan tag in the user data and then forwards the pseudo-wire, while the egress PE attaches the corresponding vlan tag to the user data according to the outgoing interface type and then forwards it to the user. 1.
