>Description:
On a router, the Quagga ripd cant join the router multicast group unless the interface is in promiscous mode. Initial join seems to work but then connectivity is lost and any routes advertised to the interface is lost after timeout.

In the log:
Jun 26 17:00:18 gw01 ripd[3528]: multicast join failed, interface vr0 not running

The router is running a nanobsd build with the following driver:
FreeBSD: src/sys/dev/vr/if_vr.c,v 1.130.2.1 2008/04/11 03:41:58 yongari
FreeBSD: src/sys/dev/vr/if_vr.c,v 1.130.2.1 2008/04/11 03:41:58 yongari
>How-To-Repeat:
Install quagga on the system, attach a vr port to a network advertising routes, see routes timeout.
>Fix:
interface vr0 promisc
