Hi All,
I have a simple multicast topology set up and I am having trouble.
I can't ping the multicast group from router 4.
R1(s0/2)-------------(s0/2)R3(s0/1)--------------(s0/1)r4
All the interfaces have a "ip pim spare-mode" and all routers have ip
multicast-routing enabled.
On all routers I have "ip pim rp-address 10.1.1.1" which is the loopback
address of R1 and is reachable by all routers. The loopback also has ip pim
sparse-mode, and on R1 I have "ip igmp join 225.2.2.40" under s0/2.
I can't ping 225.2.2.40 from r4, but I can from R3. Any ideas?
Configs below.
Thanks,
Nate
