* configured auto-rp listener but no luck..
* I checked 'sh ip pim rp map' both on R3 and R2...Here is the output on R3
(same output is on R2). Any suggestions..
r3(config)#do sh ip pim rp map
PIM Group-to-RP Mappings
Group(s) 225.225.1.1/32
RP 25.25.1.1 (?), v2v1
Info source: 25.25.1.1 (?), elected via Auto-RP
Uptime: 10:52:18, expires: 00:02:57
I configured a tunnel from R2 to R3, with mroute between the ethernet
interfaces of the two routers. Here is what i found by setting the 'debug ip
mpacket' on R2.
*Apr 2 20:49:58.971: IP(0): s=25.25.1.1 (Serial1) d=224.0.1.40 (Tunnel0)
id=27239, ttl=15, prot=17, len=54(54), mforward
*Apr 2 20:49:59.007: IP(0): s=25.25.1.1 (Tunnel0) d=224.0.1.40 id=27239,
ttl=14, prot=17, len=54(54), not RPF interface
Debug output on R3 is::
2w2d: IP(0): s=25.25.1.1 (Serial1/0) d=224.0.1.40 (Tunnel0) id=28169,
ttl=15, prot=17, len=54(54), mforward
2w2d: IP(0): s=25.25.1.1 (Tunnel0) d=224.0.1.40 id=28169, ttl=14, prot=17,
len=54(54), not R
