The "midchain parent" one is very interesting. Do you have more than one tunnel?
Your route recursion is because you are ROUTING over this tunnel. Check your routing config (e.g. a 0.0.0.0 network will bring anything and everything into the tunnel) and make sure you are not. If you are ONLY using this tunnel for multicast, there is no need to move EVERY packet through the tunnel. Don't lose points that you already earned in your routing sections! When it comes to MROUTE, the problem this solves is RPF failures. You'll need that on the receiver-side only.

So "ip pim nbma-mode" is not permitted . So I created the tunnel b/w R1 and R3 and on R1 created a mroute pointing towards tunnel interface. But as soon as I give IP address on tunnel interface on R3 ; I start gettign following messages and tunnel interface goes down : *Jun 9 07:00:14.215: %TUN-5-RECURDOWN: Tunnel10 temporarily disabled due to recursive routing *Jun 9 07:00:15.215: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel10, changed state to down R3(config-if)# *Jun 9 07:00:15.251: %PIM-5-NBRCHG: neighbor 148.1.13.1 DOWN on interface Tunnel10 non DR R3(config-if)# *Jun 9 07:01:16.219: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel10, changed state to up *Jun 9 07:01:16.315: %PIM-5-NBRCHG: neighbor 148.1.13.1 UP on interface Tunnel10 *Jun 9 07:01:16.479: %ADJ-5-PARENT: Midchain parent maintenance for IP midchain out of Tunnel10 476488C0 - looped chain attempting to stack Can someone please help me in this .
