Hello,
First of all, here's my reference
http://www.cisco.com/en/US/docs/ios/12_2/ip/configuration/guide/1cfbipim.html
But I am using my own example.
I have the following topology:
[R1]
|
[R2]---[R4]
|
|
[R3]
R1 is the RP (static RP)
R3 is the sender to group 225.0.0.4.
R4 has join on it's serial interface to R2.
R1's interface to R2 is serial s1/0
All interfaces are in sparse-mode only.
I have all routers (except R4 because it's just the "host") configured with:
ip pim bidir-enable
ip pim rp-address 1.1.1.1 bidir
R2 cannot ping the group address. The debug ip mpacket on R1 has an OIL of
"null" yet the show ip mroute shows otherwise:
From R1:
R1#
*Mar 1 00:21:53.043: IP(0): s=172.12.23.3 (Serial1/0) d=225.0.0.4 id=17,
prot=1
, len=104(100), mroute olist null <---- says null
R1#show ip mroute 225.0.0.4
(some output omitted for clarity)
(*, 225.0.0.4), 00:08:35/00:02:51, RP 1.1.1.1, flags: B
Bidir-Upstream: Null, RPF nbr 0.0.0.0
Outgoing interface list:
Serial1/0, Forward/Sparse, 00:08:30/00:02:51 <- doesn't say null
Am I missing something?
Thanks,
