This topic provides targeted solutions for the resolution of common MSDP issues such as unpopulated caches or missing route advertisements.
MSDP SA Cache Not Populated
Problem: MSDP SA cache is not populated on a Cisco IOS XE Catalyst SD-WAN device when a source in a site sends traffic.
Possible Cause: Check if there are any connectivity or configuration issues between the MSDP peers.
Solution:
-
Check the MSDP peering status between the Cisco IOS XE Catalyst SD-WAN device and the device in non-SD-WAN.
-
Verify that these commands msdp-interworking and spt-only are configured in the Cisco IOS XE Catalyst SD-WAN device.
Problem: A Cisco IOS XE Catalyst SD-WAN device does not advertise the OMP SA route when it receives a MSDP SA message from a MSDP peer.
Possible Cause: msdp-interworking configuration could be missing.
Solution: Configure the msdp-interworking command in the correct VRF.
