• 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.

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

• 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.
