TE-9.3: FIB FAILURE DUE TO HARDWARE RESOURCE EXHAUST

Summary

Validate gRIBI FIB_FAILED functionality.

Procedure

  • Connect ATE port-1 to DUT port-1, and ATE port-2 to DUT port-2.

  • Establish a gRIBI connection (SINGLE_PRIMARY and PRESERVE mode) to the DUT.

  • Establish BGP session between ATE Port1 --- DUT Port1. Inject unique BGP routes to exhaust FIB on DUT.

  • Continuously injecting the following gRIB structure until FIB FAILED is received. Each DstIP and VIP should be unique and of /32. All the NHG and NH should be unique (of unique ID). DstIP/32 -> NHG -> NH {next-hop:} -> VIP/32 -> NHG -> NH {next-hop: AtePort2Ip}

  • Expect FIB_PROGRAMMED message until the first FIB_FAILED message received.

  • Validate that traffic for the FIB_FAILED route will not get forwarded.

  • Pick any route that received FIB_PROGRAMMED. Validate that traffic hitting the route should be forwarded to port2
