VSD-domain type VRF-GRE

VRF-GRE VSD-domains are associated with VPRN services configured without a static route-target. In this case, the VSD pushes a route-target that the router adds to the VPRN service. The system checks whether the VPRN service has a configured policy:

• If there is no vrf-import policy, the received dynamic route-target is added in the vprn> context.

• If there is a vrf-import policy, the dynamic route-target ia added to the policy, in an auto-created community that is shown with the following format: ‟VSD_svc-id” in a similar way as in L2-DOMAINs.

  Note: In cases where a vrf-import policy is used, the user provisions the WAN route-target statically in a vrf-export policy. This route-target is also used for the routes advertised to the DC.

An example of the auto-generated entry is shown below:

*A:PE# show router policy "policy-1" 
    entry 1000 # automatic VSD-generated entry
        from
            community "_VSD_1"
            family vpn-ipv4
        exit
        action accept
        exit
    exit
