At which point are you seeing these PIM messages? - at the receiving end
via tcpdump? (which occurs prior to iptables).
What is the output of ‘show pim interface’ and ‘show logging’ (looks
like you have pimsm4 traceoptions enabled).
Your kernel is configured to support mcast correct? (see section 15.3.1 of
the 1.6 manual)

Dear Garry Peirce,,
Thanks for your reply.
Yes, I can ping between two routers.
And monitoring Router #1 on ‘eth1’ (or Router #2 on ‘eth0’),
I can see PIM Hello Message from 10.3.2.18 to 224.0.0.13 and 10.3.2.20 to
224.0.0.13 periodically.
However, nothing added on Router #1.
Xorp> show pim neighbors
Interface DRpriority NeighborAddr V Mode Holdtime Timeout
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Do I have to check internal XORP process on receiving PIM Hello message?
Sincerely yours,
S. K. Jo

I assume you can ping between your routers?
You might verify that there are no FW rules on these routers blocking PIM
traffic (224.0.0.13).

Subject: [Xorp-users] Question on XORP PIM-SSM Configuration
Hi,
I’m new to XORP and now configuring simple PIM-SSM test scenario with two
XORP routers and VLC server/client.
Detailed configuration information is as below.
Multicast Server
192.168.96.49 / 24
Window XP SP3
VLC Server
Router #1
eth0: 192.169.96.50 / 24
eth1: 10.3.2.18 / 16
Fedora Core 9 / 2.6.25-14
Manually configured
as RP
Router #2
eth0: 10.3.2.20 / 16
eth1: 192.168.97.50 / 24
Multicast Client
192.168.97.49 / 24
Fedora Core 10 / 2.7.41
VLC Client
When I start to run xorp with boot configuration (see attached files), I
can check Wiresharks and each router sends ‘PIM Hello’ message.
However they can’t update their neighbor table.
Xorp> show pim neighbors
Interface DRpriority NeighborAddr V Mode Holdtime Timeout
Do I need to configure more additional information or pre-configuration?
(I read some articles about PIM-SSM posted on xorp-user group and tried it.
But it couldn’t help)
Please let us know how it goes.
Sincerely yours,
S. K. Jo
