pimd & dlink dgs-3627g

[lego12239]

Hello.

I have the next configuration with dlink dgs-3627g and pimd that doesn't
work:

multicast server
| 192.168.100.2/24
|
v 192.168.100.1/24
pimd
| 192.168.77.8/24
|
v 192.168.77.1/24
dgs-3627g
| 192.168.200.1/24
|
v 192.168.200.2/24
client

If i connect a client computer instead of dgs-3627g, everything work well.
But if i insert between pimd and client dgs-3627g multicast doesn't pass
through.
With tcpdump i see that switch send join request, but pimd simply ignore
them (though, a dgs-3627g ip is shown as a neighbor).
So, i doesn't know, is it a misconfiguration, incompabitility or bug.

I get last pimd sources from a git.

Sorry, not a clue really. Maybe the D-Link router does not support PIM-SM v2?

No. dgs-3621g supports pim-sm v2. Now i think, that the problem is in
misconfiguration. I'll check this assumption and write you more details.

Sorry, I guess I should have been a little bit more clear in my previous answer. The USC pimd implements RFC2362 predating the actual PIMv2 standard, which is defined in RFC4601. A router implementing the latter should be compatible with pimd, but there could be compatibility options you need to check.

Btw, do you have IGMP enabled on the 192.168.200.1/24 interface on the dgs-3621g?

I don't remember any such options, but i will see at the switch docs again
at tuesday. May be i skiped anything.

Yes.

Could you check and see if pimd "peers" with the dlink? With pimd you can do a "sudo pimd -r" to get a listing of Neighbors on the right hand side of the listing.

Also, to see what pimd does wihen it receives a join from the dlink a tcpdump of the packets would be greatly appreciated! Then I can use tcpreplay in my setup and run gdb on pimd.

Thanks!

Now i have no access to a switch, but at tuesday i will do all needed tests.
