Subject: IP multicast over FR
Hi all,
101---------------102
Router 101 is connected to router 102 over frame relay. I have
configured static RP on both routers. On the serial int of 101 and 102,
I have configured "ip pim sparse mode" and "ip pim nbma". 101 can form
pim neighbourhood with 102 but not the other way round. I have
configured "ip igmp join 239.1.1.1" on the s2/0 of 102, but from 101
cannot ping 239.1.1.1. The output list is Null, even igmp can see the
group.
Could someone adivse if my configuration for IP multicast over FR is
correct or not?
Thanks in advance.
