I have an OpenBSD 4.2-stable machine with the following interfaces
(it's gross, I know :():
* bge1: connected to a OpenBSD 4.3 machine via leased line
* em1: connected to network switch
* vlan0: vlan on em1
* gif0: tunnel to the 4.3 machine
* bridge0: bridging vlan0 and gif0
bge1, em1, and vlan0 are configured with IP addresses.
If I run dvmrpd on just bge1 and em1, it works fine, and multicast
traffic is routed between subnets like I expect. However, if I also
add vlan0, dvmrpd prints this error to /var/log/daemon.log at startup:
dvmrpd[1888]: mrt_add_vif: error adding VIF: Invalid argument
and then exits ~72 seconds later after printing:
dvmrpd[5569]: fatal in dvmrpe: pipe closed
dvmrpd[1888]: fatal in parent: pipe closed
dvmrpd works fine on the 4.3 machine, but its interface setup isn't
quite as gross. It does correctly route multicast traffic from vlans
though.
I'll put together a better bug report this weekend after I can look at
dvmrpd's code some more. I thought I'd mention this briefly in case
anyone more experienced could point out something obviously wrong.
Thanks.
