>Description:
Multicast not working in ripd.
I recieve tonns of messages like:
Jul 1 15:35:24 wizard ripd[68677]: Can't setsockopt IP_MULTICAST_IF on fd 11
to source address 172.16.0.7 for interface gre14
gre14 (like any other gre interface) may look like:
# ifconfig gre14
gre14: flags=b051<UP,POINTOPOINT,RUNNING,LINK0,LINK1,MULTICAST> metric 0 mtu
1476
tunnel inet 89.250.210.69 --> 89.250.210.142
inet 172.16.0.6 --> 172.16.0.7 netmask 0xffffffff
Packets sent to 224.0.0.9:520 cannot traverse gre interface, and they go using
default route.
However, multicast works just fine on gre interfaces in ospfd.
I use unicast and direct neighbor defining as a temporary solution.
Unfortunately, I'm stuck with the RIP as it's the only routing protocol on the
Cisco routers series 85[, 86x and I have lots of these.
I have filled a bug in quagga's bugzilla, but noone reacted so far.
>How-To-Repeat:
Install FreeBSD net/quagga port, get one of the low-end Cisco routers,
confugure RIP, see the logs.
>Fix:
None known.
