TE-3.7: Base Hierarchical NHG Update

Summary

Validate NHG update in hierarchical resolution scenario

Procedure

Connect ATE port-1 to DUT port-1, ATE port-2 to DUT port-2, ATE port-3 to DUT port-3.
Create a non-default VRF (VRF-1) that includes DUT port-1.
Establish gRIBI client connection with DUT.
Use Modify RPC to install entries per the following order, and ensure FIB ACK is received for each of the AFTOperation:
- Add 203.0.113.1/32 (default VRF) to NextHopGroup (default VRF) containing one NextHop (default VRF) that that specifies DUT port-2 as the egress interface and 00:1A:11:00:00:01 as the destination MAC address.
- Add 198.51.100.0/24 (VRF-1) to NextHopGroup (default VRF) containing one NextHop (default VRF) specified to be 203.0.113.1/32 in the default VRF.
TODO: Ensure that ATE port-2 receives the packets with 00:1A:11:00:00:01 as the destination MAC address.
Use the Modify RPC to add the following entries with an implicit in-place replace (ADD operation):
- Add a new NH with egress interface that specifies DUT port-3 as the egress interface and 00:1A:11:00:00:01 as the destination MAC address.
- Add the same NHG (for 203.0.113.1/32) but pointing to the new added NH.
TODO: Ensure that ATE port-3 receives the packets with 00:1A:11:00:00:01 as the destination MAC address.
