Hi ,
Tried IE WB Lab 5 , Multicast topology with a small change. & i was
able to ping spoke (src) to spoke (rcv) without nbma-type if RP is
HUB.
If i change the RP to spoke R5 (150.1.5.5) and trying pinging R5's
igmp join addresses from R2. Ping does not go through....Irrespective
of Hub has "ip pim nbma" or not.
Can you help me understand, whats the problem ?
R2 (p2p interface ...changed to ip ospf network nbma )
R3 (physical interface) (HUB)
R5 (Physical interface) (Static RP)
I have spoke to spoke PVC.
I assume the problem is because of this: ""mtrace & traceroute does
not match.""
Spoke R5
