The Tier-0 gateway must establish a connection to each of the upstream Layer 3 devices before BGP updates can be exchanged. Verify that the NSX-T Edge nodes are successfully peering and that BGP routing is established.

Use the get route bgp command to verify that you are receiving routes by using BGP and that multiple routes to BGP-learned networks exist. Figure 28 shows the truncated output of get route bgp. The networks that are shown are BGP routes (represented by the lowercase b) and are available using 172.16.47.1 (sfo01-leaf1a) and 172.16.48.1 (sfo01-leaf1b). This verifies successful BGP: Peering and ECMP enablement for all external networks.
