I have a problem with configuring auto-rp. Here's my network below:
R1====FR Network =====R2
|
R3======R4=====R5
* FR network is using all physical interfaces. R4 is the hub while R1 & R2
are both spokes.
* all interfaces are configured as sparse-dense-mode.
I have configured several join-groups in R2, and I am trying to make R2 & R5
the candidate-RPs (each router serves a different set of Multicast groups).
Also, I have configured R1 and R3 as mapping agents. R3 is working fine and
dandie as the Mapping agent (verified by "debug ip pim auto" and "show ip
pim rp mapping") and receives rp-announce multicast (224.0.1.39) from both
R5 and R2. However, R1 can't seem to receive any rp-announce msg from R2.
I have no ACL configured in this network and the broadcast statements are
under R1 & R2. Also, I tried using "ip pim nbma-mode" but that didn't help.
I am leaning towards a FR issue. Any help and suggestions would be
appreciated.
Thanks in advance,
Tony Ng
