Dear All
I have the following topology
|---R2---|
R1-(LAN2)--| |-(LAN1)-- Source
|---R3---|
there are two multi-access LANs. The R2 is elected as PIM DR on both LANs.
R3 has a better ospf cost 5 for the shared subnet towards the Source on LAN1. R2 has an OSPF cost 10.
So on R1 i see the following
(S,G) with RPF R2*
sh ip rpf S shows via R3.
I enabled the PIM debug and found that R2 is advertising an Assert message with metric 0/0. So it becomes a winner.
I even tried to move PIM DR to R3 for both subnets, by increasing DR priority on R3 interfaces.
Anybody has an idea how can I force to send multicast traffic via R3?
