RT-2.6: IS-IS Hello-Padding enabled at interface level

Summary

  • Base IS-IS functionality and adjacency establishment.
  • Verifies isis adjacency by changing MTU.

Procedure

  • Configure IS-IS for ATE port-1 and DUT port-1.
  • Configure DUT with global hello-padding enabled.
  • Ensure that adjacencies are established with:
    • Interface level hello padding is enabled.
    • Verify that IPv4 and IPv6 IS-ISIS adjacency comes up fine.
    • Verify the output of ST path displaying the status of ISIS hello padding.
    • If we change the MTU on either side, then adjacency should not come up.
    • Verify that IPv4 and IPv6 prefixes that are advertised by ATE correctly installed into DUTs route and forwarding table.
    • TODO-Verify the Hellos are sent with Padding during adjacency turn-up if the padding is enabled adaptively/sometimes.
    • Ensure that IPv4 and IPv6 prefixes that are advertised as part of an (emulated) neighboring system are installed into the DUT routing table, and validate that packets are sent and received to them.
