TE-3.6: ACK in the Presence of Other Routes

Summary

Ensure that ACKs are received in the presence of other routes.

Procedure

  • Connect DUT port-1 to ATE port-1, DUT port-2 to ATE port-2, DUT port-3 to ATE port-3. Assign IPv4 addresses to all ports.

  • Configure static routes on the DUT for 203.0.113.0/24 pointing to ATE port-2. Ensure that the static route is installed in the DUT.

  • Connect gRIBI client to DUT specifying persistence mode PRESERVE, SINGLE_PRIMARY client redundancy in the SessionParameters request, and make it become leader. Ensure that no error is reported from the gRIBI server.

  • Add an IPv4Entry for same prefix 203.0.113.0/24 pointing to ATE port-3 via gRIBI-A, ensure that the entry is active through AFT telemetry and correct ACK is received – InstalledInRIB.

  • Send traffic from ATE port-1 to prefix 203.0.113.0/24, and ensure traffic flows 100% using the static route configured at ATE port-2.
