[Xorp-users] Multicast problems

[Calum]

Hello all,


I have a very simple network here (as I don't have enough machines to
make a more complicated one!).

Source
     |
Router
     |
Client


Source and Router are running XORP - they are neighbors in show pim
neighbors and seem to be exchanging information fine (holding RP
elections, etc)

Source is sending traffic out to a multicast address, and that traffic
can be seen at Router (on the interface connected to Source).


Client joins the group (using a c program), and Router sees the join:

[ 2006/04/01 16:19:52 TRACE xorp_igmp MLD6IGMP ] RX
IGMP_V2_MEMBERSHIP_REPORT from 10.0.0.30 to 229.9.9.9 on vif eth2
[ 2006/04/01 16:19:52 TRACE xorp_pimsm4 PIM ] Add membership for
(0.0.0.0, 229.9.9.9) on vif eth2
[ 2006/04/01 16:19:52 TRACE xorp_pimsm4 PIM ] Add MFC entry:
(10.0.0.121, 229.9.9.9) iif = 1 olist = O.O olist_disable_wrongvif =
.O.
[ 2006/04/01 16:19:54 TRACE xorp_igmp MLD6IGMP ] RX
IGMP_V2_MEMBERSHIP_REPORT from 10.0.0.30 to 229.9.9.9 on vif eth2

However, Router doesn't start forwarding the traffic from Source to
229.9.9.9 to Client.
It still comes in, but doesn't get forwarded anywhere.

What's that stuff about "disable_wrongvif", by the way?
