TE-11.2: Backup NHG: Multiple NH

Summary

Ensure that backup NHGs are honoured with NextHopGroup entries containing >1 NH.

Procedure

• Connect ATE port-1 to DUT port-1, ATE port-2 to DUT port-2, ATE port-3 to DUT port-3, and ATE port-4 to DUT port-4.
• Connect a gRIBI client to the DUT and inject an IPv4Entry for 1.0.0.0/8 pointing to a NextHopGroup containing:
  • Two primary next-hops:
    • 2: to ATE port-2
    • 3: to ATE port-3
  • A backup NHG containing a single next-hop:
    • 4: to ATE port-4
• Ensure that traffic forwarded to a destination in 1.0.0.0/8 is received at ATE port-2 and port-3. Validate that AFT telemetry covers this case.
• Disable ATE port-2. Ensure that traffic for a destination in 1.0.0.0/8 is received at ATE port-3.
• Disable ATE port-3. Ensure that traffic for a destination in 1.0.0.0/8 is received at ATE port-4.
