To validate the BGP connection status between the Tier-0 Gateway and the upstream physical router on an NSX Edge node, the correct sequence involves enabling the specific logical router (Tier-0 Gateway), checking the VRF (Virtual Routing and Forwarding) context, and then using the show bgp neighbor command to view the BGP session status.
enable <LR-D>: This command enables the logical router interface (Tier-0 Gateway) to access its configuration.
get vrf <ID>: This command checks the specific VRF (used for routing separation) to see the associated routing table.
show bgp neighbor: This command displays the status of the BGP connection, including details about the neighbor relationships and their state.
