RT-1.55: BGP session mode (active/passive)

Summary

  • Validate the correct behavior of BGP session establishment in both active and passive modes.
  • Verify the accurate reflection of BGP transport mode in telemetry output.
  • Confirm the functionality of passive mode configuration at both the neighbor and peer group levels.

Topology

DUT Port1 (AS 65501) ---eBGP --- ATE Port1 (AS 65502)

Procedure

  • Configure both DUT and ATE to operate in BGP passive mode under the neighbor section.
  • Verify that the BGP adjacency will not be established.
  • Verify the telemetry path output to confirm that the neighbor's BGP transport mode is displayed as "passive for the DUT.
  • Configure BGP session on ATE to operate in BGP active mode when interacting with DUT.
  • Verify that a BGP adjacency is established between the ATE and DUT
  • Verify the telemetry path output to confirm that the neighbor's BGP transport mode is displayed as "passive for the DUT.
  • Redo the same above steps but configure the passive mode under the peer group instead of the bgp neighbor configuration.
