I have the following scenario. The IGP running is OSPF
on r1 thru r6. On r5 I am doing multicast pim
sparse-mode. r5 is the RP, r6 is joining group
239.1.1.1. There is a tunnel between r1 and r5 with
with pim sparse-mode and the appropriate ip mroutes on
r1 and r5. The issue I am having is that it will
originally work but then the tunnel will flap and go
down. Do I need to make the tunnel interfaces passive
so OSPF does not send advertisements via the Tunnel?
Making the interfaces passive seems to keep them up
and not mess up OSPF. So I am basically trying to
confirm if this is a must whem doing tunneling in
multicast.
Comments and Advice is greatly appreciated
