TE-14.1: gRIBI Scaling

Summary

Validate gRIBI scaling requirements.

Procedure

  • Connect ATE port-1 to DUT port-1, ATE port-2 to DUT port-2.
  • Create 64 L3 sub-interfaces under DUT port-2 and corresponding 64 L3 sub-interfaces on ATE port-2
  • Establish gRIBI client connection with DUT negotiating FIBACK as the requested ack_type.
  • Using gRIBI Modify RPC install the following IPv4Entry sets, and validate the specified behaviours:
    • IPv4Entries -> NHG -> Multiple NH.
      • Inject IPv4Entries(IPBlockDefaultVRF: 198.18.196.1/22) in default VRF
      • Install 64 L3 sub-interfaces IP to NextHopGroup containing one NextHop specified to ATE port-2.
      • Validate that the entries are installed as FIB_PROGRAMMED
    • IPv4Entries -> Multiple NHG -> Multiple NH.
      • Inject IPv4Entries(IPBlock1: "198.18.0.1/18") in VRF1.
      • Install 1000 IPs from IPBlockDefaultVRF to 10 NextHopGroups containing 100 NextHops each
      • Validate that the entries are installed as FIB_PROGRAMMED
    • IPv4Entries -> Multiple NHG -> Multiple NH.
      • Inject IPv4Entries(IPBlock2: "198.18.64.1/18") in VRF2.
      • Install repeat 17.5K NH from 1K /32 from IPBlockDefaultVRF to 35 NextHopGroups containing 45 NextHops each
      • Validate that the entries are installed as FIB_PROGRAMMED
    • IPv4Entries -> Multiple NHG -> Multiple NH.
      • Inject IPv4Entries(IPBlock3: "198.18.128.1/18") in VRF3.
      • Install IPiniP decap-then-encap to 500 first /32 from to 500 NextHopGroups containing 1 NextHop each
      • Validate that the entries are installed as FIB_PROGRAMMED
  • TODO: Add flows destinating to IPBlocks and ensure ATEPort2 receives it with no loss
