Using OTV links to distribute DC multicast traffic, ISR Routers

OTV Setup.PNG

 

I have three DCs that I am preparing a configuration for. The plan is to use ISR4000-series routers and interlink the three sites with OTV. Initially was planning on using the Unicast-OTV mode. Staging a simplex setup, with no redundancy yet. Mapped traffic is untagged. The architecture above is showing the sketch and the OTV-related configuration for the East and West routers, the South configuration is identical to East and therefore omitted.

 

OTV unucast/broadcast work as expected. However, one thing I ran into was that the multicast generated on West Data Center is not propagating to the East nor South. I tried using Unicast-based overlay and Multicast-based overlay and had no success with either (the configuration above is from the Unicast-based overlay configuration example).

 

Would appreciate any suggestions.

 

Thank you.
