RT-2.1: Base IS-IS Process and Adjacencies

Summary

Base IS-IS functionality and adjacency establishment.

Procedure

  • Basic fields test
    • Configure DUT:port1 for an IS-IS session with ATE:port1.
    • Read back the configuration to ensure that all fields are readable and have been set properly (or correctly have their default value).
    • Check that all relevant counters are readable and are 0 since the adjacency has not yet been established.
    • Push ATE configuration for the other end of the adjacency, and wait for the adjacency to form.
    • Check that the various state fields of the adjacency are reported correctly.
    • Check that error counters are still 0 and that packet counters have all increased.
  • Hello padding test
    • Configure IS-IS between DUT:port1 and ATE:port1 for each possible value of hello padding (DISABLED, STRICT, etc.)
    • Confirm in each case that that adjacency forms and the correct values are reported back by the device.
  • Authentication test
    • Configure IS-IS between DUT:port1 and ATE:port1 With authentication disabled, then enabled in TEXT mode, then enabled in MD5 mode.
    • Confirm in each case that that adjacency forms and the correct values are reported back by the device.
  • Routing test
  • 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.
