Ensure that gRIBI programmed operations result in the correct traffic forwarding behaviour on the DUT.

• Configure DUT port-1 to be connected to ATE port-1, and DUT port-2 to be connected to ATE port-2. ATE port-2 is configured to have an assigned address of 198.18.2.2, and the interface is enabled.
• For label stack depths beginning at baseLabel, with numLabels addition labels:
  • Program a LabelEntry matching outer label 100 pointing to a NHG containing a single NH.
  • Program a NextHopEntry which points to 192.18.2.2 pushing [baseLabel, ..., baseLabel+numLabels] onto the MPLS label stack.
• Run an MPLS flow matching label 100's forwarding entry and validate that is received at the destination port.

• Configure DUT port-1 to be connected to ATE port-1, and DUT port-2 to be connected to ATE port-2. ATE port-2 is configured to have an assigned address of 198.18.2.2, and the interface is enabled.
• For label stack depth beginning at baseLabel, with numLabels addition labels:
  • Program a IPv4Entry matcing IP Prefix 192.168.0.0/24 pointing to a NHG containing a single NH.
  • Program a NextHopEntry which points to 192.18.2.2 pushing [baseLabel, ..., baseLabel+numLabels] onto the MPLS label stack.
• Run an IP flow matching IP Prefix 192.168.0.0/24 and validate that it is received at the destination port.
