Hi!

I need quagga to add default route to ng1 interface (without specifying next-hop address)
when there is no default route yet.

So, I use command 'ip route 0.0.0.0/0 ng1' and it tries to add it to the kernel
and fails. Its debug shows:

2011/11/27 02:44:05 ZEBRA: rib_process: 0.0.0.0/0: Adding route, select 0x2125f220

2011/11/27 02:44:05 ZEBRA: kernel_rtm_ipv4: No useful nexthops were found in RIB entry 0x2125f220

Meantime, 'route -n monitor' shows:

got message of size 116 on Sun Nov 27 02:57:03 2011
RTM_ADD: Add Route: len 116, pid: 566, seq 87, errno 51, flags:<UP,PROTO1>
locks:  inits: 
sockaddrs: <DST,GATEWAY,NETMASK>
 default default default

If I use command 'route add default -iface ng1', it succeedes and I see differing picture:

got message of size 168 on Sun Nov 27 02:53:47 2011
RTM_ADD: Add Route: len 168, pid: 2817, seq 1, errno 0, flags:<UP,DONE,STATIC>
locks:  inits:
sockaddrs: <DST,GATEWAY,NETMASK>
 default ng1 default

It seems, quagga does not pass interface name ng1 to the kernel.
Does someone know how to fix it quick? I use 8.2-STABLE/amd64 and quagga-0.99.20 from ports.
