Ensure that IS-IS updates reflect parameter changes on DUT.

• Configure L2 IS-IS adjacency between ATE port-1 and DUT port-1, and ATE port-2 and DUT port-2.

• Validate that received LSDB on ATE has:

  • TODO: Overload bit unset by default, change overload bit to set via DUT configuration, and ensure that the overload bit is advertised as set (as observed by the ATE). Ensure that DUT telemetry reflects the overload bit is set.

  • TODO: Metric is set to the specified value for ATE port-1 facing DUT port via configuration, update value in configuration, and ensure that ATE and DUT telemetry reflects the change.
