Overview

Use this procedure to confirm that protocol interoperability is active and that remote nodes are correctly identified within the overlay.

Procedure

The following is a sample output from the show platform software sdwan multicast remote-nodes vrf 1 command, which shows if MSDP interoperability is enabled or not.

Example:

Device# show platform software sdwan multicast remote-nodes vrf 1
