RT-2.1: Base IS-IS Process and Adjacencies

Summary

Base IS-IS functionality and adjacency establishment.

Procedure

  • Configure IS-IS for ATE port-1 and DUT port-1.
    • Configure DUT with global hello padding set to DISABLED accepted. Interface-specific ISIS hello padding configuration not accepted.
  • Ensure that adjacencies are established with:
    • Hello authentication enabled.
    • Global hello padding disabled.
  • With ISIS level authentication enabled and hello authentication enabled:
    • Ensure that IPv4 and IPv6 prefixes that are advertised as attached prefixes within each LSP are correctly installed into the DUT routing table, by ensuring that packets are received to the attached prefix when forwarded from ATE port-1.
    • 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.
  • With a known LSP content, ensure that the telemetry received from the device for the LSP matches the expected content.
