Are you sure ACL 1 is configured on all devices? Need to follow the join backwards from SW4 towards the RP.

Here's my setup. I've got SW4----various devices----R5 (RP) -----various devices ----- R6. R6 is my source and I try to ping two different MC groups that SW4's L0 has joined. Everyone is set for a static RP, which is R5's L0 address (155.1.1.5). Their RP address command is ip pim rp-address 155.1.1.5 1 where ACL 1 is permit 224.0.0.0 0.255.255.255. So, R6 pings 239.0.0.1 and the ping succeeds, giving me the following MROUTE entries on R5: (*, 239.0.0.1), 00:00:25/stopped, RP 0.0.0.0, flags: D Incoming interface: Null, RPF nbr 0.0.0.0 Outgoing interface list: FastEthernet0/1, Forward/Sparse-Dense, 00:00:25/00:00:00 Serial1/1, Forward/Sparse-Dense, 00:00:25/00:00:00 (155.1.146.6, 239.0.0.1), 00:00:25/00:02:38, flags: T Incoming interface: Serial1/1, RPF nbr 155.1.45.4 Outgoing interface list: FastEthernet0/1, Forward/Sparse-Dense, 00:00:26/00:00:00 OK, this makes sense. Traffic for the S,G comes in from R6 via S1/1 and goes out F0/1 toward SW4. All working as expected. 239.0.0.1 is a dense mode group because it's not covered by ACL1. So, then we check our MROUTE for the 224.30.30.30 group. (*, 224.30.30.30), 00:00:36/stopped, RP 155.1.1.5, flags: SP Incoming interface: Null, RPF nbr 0.0.0.0 Outgoing interface list: Null (155.1.146.6, 224.30.30.30), 00:00:36/00:02:24, flags: P Incoming interface: Serial1/1, RPF nbr 155.1.45.4 Outgoing interface list: Null Pruned with extreme prejudice. It has an RP, and the RP is reachable. Why am I getting the prune? Anyone? _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
