RT-7.4: BGP Policy AS Path Set and Community Set

Summary

BGP policy configuration for AS Paths and Community Sets

Procedure

  • RT-7.4.1 - Test setup

    • Generate config for 2 DUT ports, with DUT port 1 eBGP session to ATE port 1.

    • Generate config for ATE 2 ports, with ATE port 1 eBGP session to DUT port 1.

    • Configure ATE port 1 to advertise ipv4 and ipv6 prefixes using the following aspaths and communities:

      • prefix-set-1 with as path [100, 200, 300] and communities [100:1, 200:2, 300:3]
      • prefix-set-2 with as path [100, 400, 300] and communities [101:1]
      • prefix-set-3 with as path [109] and communities [109:1]
      • prefix-set-4 with as path [200] and communities [200:1]
      • prefix-set-5 with as path [300] and communities [100:1]

    • Establish eBGP sessions between ATE port-1 and DUT port-1

    • Generate traffic from ATE port-2 to all prefixes

    • Validate that traffic is received on ATE port-1 for all prefixes

  • RT-7.4.2 - Validate single routing-policy containing as-path-set and ext-community-set

    • Create a as-path-set named any_my_regex_aspath with members

      • { as-path-set-member = [ "(10[0-9]]|200)" ] }

    • Create a community-set named any_my_regex_comms with members and match options as follows:

      • { community-member = [ "10[0-9]:1" ] }

    • Create a policy-definition named 'path_and_community' with the following statements

      • statement[name='match_community']/
        • conditions/bgp-conditions/match-community-set/config/community-set = 'any_my_regex_comms'
        • conditions/bgp-conditions/match-community-set/config/match-set-options = ANY
        • actions/config/policy-result = ACCEPT_ROUTE
      • statement[name='match_as']/
        • conditions/bgp-conditions/match-as-path-set/config/as-path-set = 'any_my_regex_aspath'
        • conditions/bgp-conditions/match-as-path-set/config/match-set-options = ANY
        • actions/config/policy-result = ACCEPT_ROUTE

    • Send traffic

      • Verify traffic is forwarded for routes with matching policy
      • Verify traffic is not forwarded for routes without matching policy

Expected prefix matches

prefix-set path_and_community
prefix-set-1 accept
prefix-set-2 accept
prefix-set-3 accept
prefix-set-4 reject
prefix-set-5 reject
