5 ACI L4 L7 Service Insertion Overview

6 Traditional Network Service Insertion Challenges Router Configure Network to insert Firewall FW Configure firewall network parameters Service insertion takes days vfw Router Switch LB Configure firewall rules as required by the application Configure Load Balancer Network Parameters Configure Router to steer traffic to/from Load Balancer Network configuration is time consuming and error prone Difficult to track configuration on services Server Service Insertion In traditional Networks Configure Load Balancer as required by the application F5 Networks, Inc 6

8 Distributed Management Information Tree (dmit) Objects within APIC are structured in tree-based hierarchy Objects referred to as managed objects (MO) Packages identify the functional area e.g., fabric = physical fabric, ADC= F5 BigIP etc.. Every object has a parent, with exception of top:root (top of tree) Relationships exist between objects using Distinguished Name or DN. F5 Networks, Inc Cisco Public 8

9 F5 Device Package: Definition APIC requires a Device Package to communicate with service devices. A Device Package is a zip file containing two parts: Device Specification (xml): The configuration of the APIC is represented as an object model consisting of a large number of Managed Objects (MOs). A Device type is defined by a tree of MOs with a Meta Device (MDev) at the root. Configuration through UI or North Bound APIs APIC EPG level L4-L7 config Service Graph Function Node level L4-L7 config DeviceScript (py): The integration between the APIC and a Device is performed by a DeviceScript, which maps APIC events function calls defined in Device Script Python Device Script Device Package icontrol / SouthBound API BIG-IP Physical or VE Device Specification <dev type= f5 > <service type= slb > <param name= vip > <dev ident= <validator= ip <hidden= no > <locked= yes > F5 Networks, Inc 9

10 Logical Device Cluster / Concrete Device: Definition Logical Interfaces Map to concrete devices interfaces Tenant admin connects concrete Device to the fabric and assigns management IP. Tenant admin registers device with APIC. APIC validates device using device specs from device package Concrete Device Concrete Device Logical Device Cluster Represents service device (physical or virtual), for example an ADC or FW Represents a cluster of 2 devices that operate in active/standby mode for instance FCS : Supporting device clusters with maximum of two concrete device in active-standby mode F5 Networks, Inc 10

11 Service Graph: Definition Abstract graph concept mapping to Service Graph Consumes Functions rendered on the same device Service Graph: web-application Provides EXT EXT EXT EXT Func: Firewall Func: SSL offload Func: Load Balancing WEB WEB WEB WEB EPG - EXT Terminals Connectors Terminals EPG - WEB Firewall params Permit ip tcp * dest-ip <vip> dest-port 80 Deny ip udp * SSL params Ipaddress <vip> port 80 Load-Balancing params virtual-ip <vip> port 80 Lb-aglorithm: round-robin Service graph is an ordered set of functions between a set of terminals e-g; Firewall Function, Load balancer Function A function has one or more connectors Network connectivity like VLAN/VNID tag is assigned to these connectors A function within a graph may require one or more parameters Parameters can be scoped by an EPG or an application profile or tenant context Parameter values can be locked from further changes F5 Networks, Inc 11

23 F5 BIG-IP LTM Integration with Cisco ACI Using Device Package and ACI 1.0(2m)

24 Terminology: APIC Tenant Single Context / BIG-IP Partition Tenant is a container for policies (filters, contracts, bridge domains and application profiles) BIG-IP partition is equivalent to a single context ACI tenant A function node identifies a set of network service functions that are required by an application BIG-IP Virtual Server is equivalent to service graph function node F5 Networks, Inc 24

25 Terminology: APIC Service Graph Config pushed to BIG-IP APIC Service Graph Function Node Config Parameters, for example, webpool, will be pushed from APIC to BIG-IP In this example, BIG-IP populates Pool configuration from APIC. F5 Networks, Inc 25

26 Device Package Feature: Referencing irules APIC can reference irules that resides in BIG-IP Common partition BIG-IP is responsible for irules management, including creation / modification / validation F5 Networks, Inc 26

27 Mixed Mode Support Client EPG Contract: Including L4-L7 services Server EPG Client EPG Contract BIG-IP Ext EPG BIG-IP Int EPG Contract Server EPG APIC APIC Partition Configuration pushed and populated by APIC. User does not modify this partition. APIC will perform L4-L7 service insertion on this partition. BIG-IP created Partition: User can continue to use partition created by BIG-IP, they appeared as separate EPG to APIC. Network functionality will be managed by APIC through the Fabric, where L4-L7 will be managed by BIG-IP. User can continue to use custom iapp and irules in this scenario. Common Partition User can define custom irules under Common partition and they can be called by APIC, BIG-IP Physical or Virtual F5 Networks, Inc 27

29 Monitoring: Device Health Score Device Health Score indicates BIG-IP health base on internal BIG-IP algorithm F5 Networks, Inc 29

30 Monitoring: Service Health Score Service Health Score indicates virtual server health base on internal / external interfaces state, plus pool availability F5 Networks, Inc 30

31 Troubleshooting: APIC Faults / Visore / debug.log / LTM log APIC Faults /data/devicescript/f5.bigip.1.1.0/logs/debug.log /var/log/* F5 Networks, Inc 31

32 Automation: REST API APIC is based on a hierarchical object model. EVERYTHING is represented as an object and every object can be manipulated via REST. REST operations: POST, GET, DELETE Support for JSON and XML Format: class}/{dn classname}.{json/xml}[?options] /api/ Specifies that the message is directed to the API. mo class Specifies whether the target of the operation is a managed object (MO) or an object class. Dn Specifies the distinguished name (DN) of the targeted MO. classname Specifies the name of the targeted class. This name is a concatenation of the package name of the object queried and the name of the class queried in the context of the corresponding package. For example, the class aaa:user results in a classname of aaauser in the URI. json xml Specifies whether the encoding format of the command or response HTML body is JSON or XML. F5 Networks, Inc 32

38 F5 is Industry Leader in Application Delivery How can we provide full set of F5 functionality to ACI environment that is application focused? F5 has an extensive library of iapps for deploying applications F5 Networks, Inc 38

39 What are iapps? An iapps is an application-centric configuration template: User answers a few questions about deploying an application iapps translates answers into a set of configuration options iapps can touch almost all BIG-IP functionality irules, profiles, monitors, security policies, and much more There are many F5-provided iapps: HTTP, Sharepoint, Exchange, VMware View, Users can build their own iapps F5 Networks, Inc 39
