RT-10.2: Non-default Route Generation based on 192.168.2.2/32 Presence in ISIS

Testcase summary

Testbed type

Topology

  • Connect ATE Port-1 to DUT Port-1

  • Preconditions:

    • A ISIS speaker DUT is configured.

    • ISIS peering is established and stable between DUT and at least one neighbor ATE-1.

    • A policy to generate default route 192.168.2.0/30 upon receiving a isis route 192.168.2.2/32

    • Initial routing tables are verified to be free of any 192.168.2.0/30 or 192.168.2.2/32 .

Procedure for generate non-default route

Scenario: 192.168.2.2/32 route is present

1.1 On ATE-1, advertise a isis route 192.168.2.2/32 towards DUT.

Expected result: The 192.168.2.2/32 route is visible in DUT's routing table.

1.2 Wait for isis to converge.

Expected result: The isis session remains in the UP state.

1.3 On DUT, inspect the routing table.

Expected result: A non-default route (192.168.2.0/30) is now generated in DUT.

1.4 On ATE-1, stop advertising the route 192.168.2.2/32.

Expected result: The 192.168.2.2/32 route is removed from DUT's routing table.

1.5 Wait for isis to converge.

Expected result: The isis session remains in the UP state.

1.6 On DUT, inspect the routing table.

Expected result: The non-default route 192.168.2.0/30 is withdrawn and is no longer generated in DUT.

Conclusion:

Pass: The test case passes if all expected results are achieved.

Fail: The test case fails if any of the following occur:

A non-default route is generated and when the 192.168.2.2/32 route is not present. A non-default route is not generated and advertised when the 192.168.2.2/32 route is present. The isis session drops or gets stuck in an intermediate state.

Canonical OC

TODO:

  1. Add advertise-aggregate path to the OpenConfig public data models. https://github.com/openconfig/public/issues/1368 
    /routing-policy/policy-definitions/policy-definition/statements/statement/actions/config/advertise-aggregate = `"LOCAL-AGG"
  2. Add a new OC path for attaching a routing-policy to ISIS to match the route.
  3. Add OC path for state verification as well.
