TE-6.2: Route Removal In Non Default VRF

Summary

Validate that Flush RPC in gRIBI removes routes in non-default VRF as expected.

Procedure

  • Connect ATE port-1 to DUT port-1, and ATE port-2 to DUT port-2.
  • Create a non-default VRF (VRF-1) that includes DUT port-1.
  • Connect gRIBI client (gRIBI-A) to DUT, with persistence set to PRESERVE and SINGLE_PRIMARY redundancy specified and make it become leader. Connect a second client (gRIBI-B) using the same parameters, but with election_id=leader_election_id-1.
  • Inject an IPv4Entry for 198.51.100.0/24 into VRF-1, with its referenced NHG and NH in the default routing-instance pointing to ATE port-2.
    • Ensure that packets can be forwarded between ATE port-1 and port-2 for destinations within 198.51.100.0/24.
    • Issue Flush RPC from gRIBI-A for VRF-1, ensure that entries are removed via validating packet forwarding and telemetry;
    • Re-inject entry for 198.51.100.0/24 in VRF-1 from gRIBI-A
    • Issue Flush from gRIBI-B, ensure that entries are not removed via validating packet forwarding and telemetry; expect a NOT_PRIMARY RPC response error.
    • Make gRIBI-B become leader.
    • Issue Flush from gRIBI-B for VRF-1, ensure that entries are removed via packet forwarding and telemetry.
    • Re-inject entry for 198.51.100.0/24 in VRF-1 from gRIBI-B. Re-inject entry for 198.51.110.0/24 in default VRF,from gRIBI-B, referencing the same NHG and NH pointing to port-2.
    • Ensure entries’ existence via packet forwarding and telemetry for 198.51.100.0/24. Ensure entries’ existence via telemetry for 198.51.110.0/24.
    • Issue Flush RPC from gRIBI-B for default VRF
    • Ensure that the gRIBI-B receives NON_ZERO_REFERENCE_REMAIN. Ensure that the IPEntry 198.51.100.0/24 is not removed, by validating packet forwarding and telemetry. Ensure that 198.51.110.0/24 has been removed by validating telemetry.
