1 WHITEPAPER Bringing MPLS to Data Center Fabrics with Labeled BGP
2 Bringing MPLS to Data Center Fabrics with Labeled BGP MPLS is a well-known and mature technology typically used in service provider environment. Virtual Private Network (VPN) and Traffic Engineering are the two main MPLS applications. However, MPLS can also be used in data center deployment especially to interconnect data centers to expand L2 boundary across an MPLS network. This may be a good alternative to any emerging overlay technologies such as VXLAN for service providers. This is due to the fact that service providers or even many enterprises have been using MPLS for other services. Using MPLS in data center for overlay is nothing but a natural extension for them. Moreover, they don t have to deal with another overlay technology that adds complexity and difficulty both in administration and operation. Though Labeled BGP is not a new technology, it is new in data center especially with SDN white box switches. PicOS is the first white box switch operating system to support this technology. This white paper outlines how Labeled BGP can be used as an overly solution by using PicOS on SDN white box switches. What is Labeled BGP? Labeled BGP is defined in RFC 3017 that outlines label allocation between BGP peers. Labeled BGP is very useful where MPLS network is segmented within an autonomous system (AS) or spanned across multiple-as. It provides scalability by isolating IP routing between MPLS domains or segments because core devices don t have to learn all IP routes and additionally, routes can be summarized. Figure 1 illustrates this behavior. In principle, Labeled BGP is very similar to MPLS VPN in the sense that in MPLS VPN, provider edge (PE) device allocates two labels to an unlabeled packet. In Labeled BGP, edge devices typically receive packets with two labels. The inner label identifies MPLS service and the outer label identifies LSP. In edge device, outer label is replaced with two labels and hence, resulting packet has three labels. The new outer label is used to forward packet within core network. The middle label is used to forward packet to the final edge or PE device. The third label or bottom label represents MPLS service. Figure 1. Labeled BGP 1 WHITEPAPER
3 Using Labeled BGP in the Data Center Following Microsoft and Facebook leadership, BGP is becoming the standard protocol to build CLOS based data center. Their design is described in this document: MPLS is the de-facto standard for service provider WAN or core networks. So for a service provider building a large CLOS data center that already decided to use BGP in their data center and MPLS in their core network, it is becoming an obvious choice to use Labeled BGP to have an end-to-end MPLS network. Labeled BGP can be used in the data center as an overlay technology instead of VXLAN. Figure 2, illustrates Labeled BGP in data center. In this scenario, MPLS runs between OVS on VM and leaf switch, and Labeled BGP runs between data center switch and upstream router. Figure 2. Labeled BGP in the Data Center PicOS Architecture 2
4 Using different encapsulation protocol between the data center and the core brings some complexity in the network are the tunnels need to be stitched together to build an end-to-end service (see Figure 3). Those stitching mechanisms have to be built for all the services type for example L3VPN or L2VPN. Building translation between protocols also incurs the risk of loosing information and adding point of failure in the network. All those issues can be avoided by using an end-to-end MPLS LSP. Figure 3. Stitching VXLAN and MPLS in the Data Center Edge Deploying Labeled BGP in Data Center with PicOS and SDN White Box In a data center using this solution the MPLS ingress router would typically be the host itself. More precisely, the virtual switch of the data centers hosts. Very similar to how most virtual switch are using the VXLAN encapsulation. This section outlines how Labeled BGP can be deployed in data center with PicOS on SDN white box switches. In this use case, the ingress LSPs are routers simulating virtual switch in a real production network. The ToRs will receive (i.e. incoming packet) packets with two MPLS labels. However, PicOS also supports Labeled BGP solution with no (i.e. pure IP packet), one, two or three labels or more labels. But, packets with up to three labels are tested and verified. Additionally, PicOS supports label BGP for IPv4 and IPv6 as well as in ibgp and ebgp environments. LDP or 3 WHITEPAPER
5 dynamic label distribution protocol is typically used in MPLS deployment, but this is not the case in the data center. In fact, label mapping on the edge of the data center is mainly static and additionally, it is possible to run MPLS between ToR switch and OVS (or vrouter) running on hypervisors where label distribution can be done centrally. Therefore, static label allocation on ToR switches is not only acceptable but also desirable. Test Bed Configuration The test bed consists of three SDN white box switches running PicOS 2.6 and one IXIA test equipment. Figure 4 exhibits this setup. Label BGP is configured on all routers in a single AS. Router B is used, as BGP RR and routers A and C are RR clients. Next-hop-self is enabled on all routers. Static label mapping is used for MPLS label allocation in all routers. PicOS does not support LDP.H1 and H2 are IXIA based hosts used to send and receive label packets to routers A and C. Figure 4.
