I have an rpf issue I am trying to resolve.
I have 3 routers ip multicast routing, ip pim sparse, Autorp and ip pim
autorp listener configured.
I can ping the igmp groups from r1 and r2 but I can not ping the groups from
r3. The groups are configured on r3. Looking at it again I sometimes the
pings will work from R1 and sometimes they do not. r3 f0/1 was saying it's
not an rfp interface. I added a mroute ong r3 pointing to r2 and it did not
do anything. I added an mroute pointing to f0/1 on r3 and it did not do
anything. Ip v4 pings to all interfaces work fine, so no unicast routing
issues.
r1, r2 and r3 and connected to each other via frame-relay. The fast
ethernets all go to different vlans.
r1 -

Any idea's?
