IP Extcommunity List

IP extcommunity lists define ordered permit/deny rules that match the BGP extended community attribute of routes. Standard lists match route targets (rt), site-of-origin values (soo), 4-byte AS generic communities (4byteas-generic transitive / non-transitive) and EVPN router MACs (rmac), while expanded lists match the extended community string with a regular expression. Extcommunity lists are referenced from route map match extcommunity and set extcomm-list ... delete clauses.

Examples

Example 1: Standard extcommunity list matching route targets and site-of-origin values

nxos:
  devices:
    - name: BORDER-LEAF1
      configuration:
        ip_extcommunity_lists:
          - name: ECL-TENANT-A
            mode: standard
            entries:
              - seq: 10
                action: permit
                rts:
                  - "65000:10010"
                  - "65000:10020"
                soos:
                  - "65000:1"
              - seq: 20
                action: deny
                4byteas_generic_transitives:
                  - "4200000001:100"

Example 2: Standard extcommunity list matching an EVPN router MAC and an expanded list using a regular expression

nxos:
  devices:
    - name: SPINE1
      configuration:
        ip_extcommunity_lists:
          - name: ECL-RMAC
            mode: standard
            entries:
              - seq: 10
                action: permit
                rmacs:
                  - "00:11:22:33:44:55"
          - name: ECL-REGEX
            mode: expanded
            entries:
              - seq: 10
                action: permit
                regex: "_65000_"
