Overview
Explains how to confirm that your centralized topology is operational and follows expected network behavior. This task involves using specific show commands to examine BFD sessions and OMP routes, ensuring that traffic is correctly following the designated hub-and-spoke paths.
Hub-and-spoke configuration verification involves confirming the correct setup and operational status of a hub-and-spoke topology within a Cisco Catalyst SD-WAN environment. This includes examining configurations on Cisco SD-WAN Controllers, individual hub and spoke routers, and observing expected network behavior.
Methods for Verifying Cisco SD-WAN Controller Configuration
Hub-and-spoke configuration makes use of transport gateways and the site type parameter, which are described in the transport gateway documentation. See Transport gateways for connecting networks in Cisco SD‑WAN.

For information about verifying a transport gateway configuration, see Verify a transport gateway configuration using the CLI.
-
For information about verifying the site type, see Verify the site type of a router using the CLI.
-
For information about verifying BFD sessions, OMP routes, and IP routes on the devices in the network after configuring hub-and-spoke, see the example in the introduction to this feature, here: Hub-and-Spoke connectivity example.
To verify that a Cisco SD-WAN Controller configuration includes the topology hub-and-spoke enable command, use the show running-config command.
In the following example, the Cisco SD-WAN Controller is configured to enable a hub-and-spoke topology.
sdwanController# show running-config
...
system
topology hub-and-spoke
enable
To verify that the topology hub-and-spoke enable command has taken effect, use the show omp summary command. The output indicates the topology. In the following example, the topology is hub-and-spoke.
sdwanController# show omp summary
per-state UP
admin-state UP
...
topology hub-and-spoke
