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

• 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.
