I am try to get a vpn multicast traffic across the MPLS cloud so sources/clients in each region have connectivity. The MSDP peer between the two region is "up" but mroute is showing NULL interface as follows:
(10.1.1.31, 224.28.28.28), 00:01:23/00:01:36, flags: PA
Incoming interface: Ethernet0/2, RPF nbr 10.10.2.2
Outgoing interface list: Null
So we need to enable multicast routing over the MPLS??
Some config is as follows:
one side:
R7#sh run | i multi|rp|bsr|pim
ip multicast-routing vrf site-b
multilink bundle-name authenticated
ip pim sparse-dense-mode
ip pim sparse-dense-mode
ip pim vrf site-b send-rp-announce Loopback100 scope 16
ip pim vrf site-b send-rp-discovery Loopback100 scope 16
R7#sh run in lo100
Building configuration...
Current configuration : 149 bytes
!
interface Loopback100
ip vrf forwarding site-b
ip address 172.1.1.7 255.255.255.255
ip pim sparse-dense-mode
ip igmp join-group 224.1.1.1
end
!
interface Ethernet0/1
ip address 172.10.12.37 255.255.255.252
mpls ip
end
The other side
MSDP is not configured on PE. Infect its on CE but i will paste the PE and CE config:
CE;
ip pim bsr-candidate Loopback0 0
ip pim rp-candidate Loopback0
R23#sh run int e0/0
