Dear Ingo,

Thanks for your help, I have found the problem..

The routes are advertised with src of the first alias of the interface, and
my host is on the 3nd network:

border-nx# sh interface eth0.1147
Interface eth0.1147 is up, line protocol detection is disabled
  index 26 metric 1 mtu 1500
  HWaddr: 00:30:48:7e:b6:08
  inet broadcast eth0.1147:17
  inet broadcast eth0.1147:11
  inet broadcast eth0.1147:9
  inet broadcast eth0.1147:5
    30799637596 input packets (329848 multicast), 34400046181696 bytes, 0
    0 input errors, 0 length, 0 overrun, 0 CRC, 0 frame
    0 fifo, 0 missed
    20281109410 output packets, 10613354085691 bytes, 0 dropped
    0 output errors, 0 aborted, 0 carrier, 0 fifo, 0 heartbeat
    0 window, 0 collisions

I can see ICMP broadcasts from, but my host has  (the
3rd network), and will silently ignore the multicasts.
They are two problems:
	1) maybe we should send an advertise for each network with it's own
source ip.  (IE:  Sent advertises on with src, sent
advertises on with, etc..)
	2) is there a way to set the src of the packets ?

Best Regards,

Dear Alexandru,

> I?m trying to make zebra export static and default route via IRDP, but so
far I only got some networks of the connected interface:

ever read the RFC?

I don't expect that this is possible or that irdp is designed for 
advertising "routes".

If you don't receive a default route at the host - than it seems its a 
host problem and not one from the advertising router "quagga".

Kind regards,
