Re: PIM BiDir Problem

Try making sure that SW4 is NOT the DR on the SW2/SW4 segment and try again. I have seen some interesting things happen that way.

Subject: PIM BiDir Problem

Hello,
I'm working on a PIM bidirectional lab and looks like i'm stuck :( I hope
some here can help me out.

The shared tree looks pretty good but no traffic response from pings. Here
are the details

R5 (RP) (Source) ---> SW2 -------------> SW4 ---| (238.10.10.10 receiver)
Gi0/0 |----| Vlan58, Po1|-------|Po1 , Vlan10

The mroute tables:

This is the RP and source
R5#sh ip mroute 238.10.10.10 | b \(
(*, 238.10.10.10), 00:06:45/00:02:30, RP *150.1.5.5*, flags: B
Bidir-Upstream: Null, RPF nbr 0.0.0.0
Outgoing interface list:
*GigabitEthernet0/0*, Forward/Sparse, 00:05:59/00:02:30

This is the intermediate router.
SW2#sh ip mroute 238.10.10.10 | b \(
(*, 238.10.10.10), 00:07:03/00:03:23, RP 150.1.5.5, flags: B
Bidir-Upstream: Vlan58, RPF nbr 155.1.58.5
Outgoing interface list:
Port-channel1, Forward/Sparse, 00:07:03/00:03:23
Vlan58, *Bidir-Upstream*/Sparse, 00:07:03/00:00:00

The receiver.
SW4#sh ip mroute 238.10.10.10 | b \(
(*, 238.10.10.10), 00:07:03/00:02:51, RP 150.1.5.5, flags: BCL
Bidir-Upstream: Port-channel1, RPF nbr 155.1.108.8
Outgoing interface list:
Vlan10, Forward/Sparse, 00:07:03/00:02:51
Port-channel1,* Bidir-Upstream*/Sparse, 00:07:03/00:00:00

*This is what I've tried so far:*
1. Verified all devices have bootstrap mappings and the group is set for
bidirectional mode.
2. "debug ip mpacket 238.10.10.10" on SW2 and SW4. RESULT: I see packets
destined to the correct group leaving R5 (the source) SW2 gets them. SW4 on
the other hand never gets these packets in the debugs ( I disabled
mroute-cache on all interface just to be sure).
3. check to make sure all of them are ip pim neighbors running
sparse/bidirectional mode.
4. Reloaded all devices.

I'm really out of ideas, if anyone has any suggestions please help.

Thank you.
