Router 1 Configuration; Router 2 Configuration - Avaya 1000 Series Configuration Manual

Configuration
When configuring PIM over GRE tunnels, you must adhere to the following points:
1. When PIM is to be run over GRE tunnels, configure the GRE tunnel IP addresses
2. When configuring PIM over GRE tunnels (with the tunnel source configured the
3. If the BSR/ RP/ Multicast Source networks reside on the other side of the tunnel,
Note:
There are no new CLI commands added for the purpose of supporting multicast over GRE
tunnels. The PIM related configurations have the same syntax as they do for Ethernet or
WAN interfaces.
The following figure shows an example configuration:

Below is the sample configuration.

Router 1 configuration

Router 1/configure> interface tunnel t1
Router 1/configure/interface t1> ip address 100.45.167.1 255.255.255.0
Router 1/configure/interface t1> tunnel source 2.2.2.2
Router 1/configure/interface t1> tunnel destination 4.4.4.4
Router 1/configure/interface t1> exit tunnel

Router 2 configuration

Router 2/configure> interface tunnel t2
Router 2/configure/interface t2> ip address 100.45.167.2 255.255.255.0
Router 2/configure/interface t2> tunnel source 4.4.4.4
Router 2/configure/interface t2> tunnel destination 2.2.2.2
Router 2/configure/interface t2> exit tunnel

at both the tunnel end-points in the same subnet. Also, it is mandatory to ensure
the reachability to the tunnel destination either using IGP or a static route.
same as the IP address of the tunnel) configuring the tunnel interface as the CBSR
or CRP is not allowed, as the RPF check will fail at the tunnel end point routers (as
result of having the 32-bit static route to the tunnel destination).
the reachability towards the BSR/ RP/ Multicast Source *should be* ensured with
the next-hop as tunnel's other end, either by IGP or static routes.
