Ensure that IS-IS metric change can drain traffic from a DUT trunk interface
- Connect three ATE ports to the DUT
- Port-2 and port-3 each makes a one-member trunk port with the same ISIS metric 10 configured for the trunk interfaces (trunk-2 and trunk-3).
- Configure a destination network-a connected to trunk-2 and trunk-3.
- Send 10K IPv4 traffic flows from ATE port-1 to network-a. Validate that traffic is going via trunk-2 and trunk-3 and there is no traffic loss
- Change the ISIS metric of trunk-2 to 1000 value. Validate that 100% of the traffic is going out of only trunk-3 and there is no traffic loss.
- Revert back the ISIS metric on trunk-2. Validate that the traffic is going via both trunk-2 and trunk-3, and there is no traffic loss.
