traceroute_packetin_test - openconfig/featureprofiles GitHub Wiki
Verify that Traceroute packets are punted with correct metadata. Verify that P4RT configurations persist after client connectivity drops. After client re-connection without programming the P4RT config verify traceroute packets are still punted.
- Connect ATE port-1 to DUT port-1, ATE port-2 to DUT port-2.
- TODO: Install the set of routes on the device.
- Enable the P4RT server on the device.
- Connect a P4RT client and configure the forwarding pipeline. InstallP4RT table entries required for traceroute.
- Send IPv4 packets from the ATE with TTL=1 and verify that packets with TTL=1 are received by the client.
- Send IPv6 packets from the ATE with HopLimit=1 and verify that packets with HopLimit=1 are received by the client.
- Verify that the packets have both ingress_singleton_port and egress_singleton_port metadata set.
- Disconnect clients
- Reconnect clients without setting P4RT config using SetForwardingPipelineConfig
- Start traffic and verify packets are punted as before
