Examples

Example 1: In Multi-Site deployments, external TEP pools serve a crucial role in enabling communication and integration with external networks and devices. The configuration below demonstrates the use of multiple external_tep_pools entries (10.10.10.0/24, 10.10.11.0/24, 10.10.12.0/24) for pod 1. This approach allows for the allocation of distinct IP address ranges for Inter-site L3Out communication.

ndo:
  sites:
    - name: NLD1
      multisite: true
      multicast_tep: 239.1.1.1
      bgp:
        as: 65009
      pods:
        - id: 1
          unicast_tep: 10.12.12.13
          external_tep_pools:
            - ip: 10.10.10.0/24
            - ip: 10.10.11.0/24
            - ip: 10.10.12.0/24
