LAB: Connecting 2 PIM Domains seperated by IP Unicast only routing domain by using a Tunnel

Basically the concept is the same as my previous Post about the Multicast Load Sharing via Tunnel.

DIAGRAM

The diagram shows that 2 PIM domains are separated via a cloud of IP Unicast Domain. a tunnel is created between the 2 edge PIM routers.
