hello!

   OSPF with Zebra again.......

   Messing up with latest zebra snapshot on latest FreeBSD-4 stable
   I've found that freebsd box running zebra+ospfd
   does not work the same way as
   cisco's and other routers on the network.

   The test was: "ping 224.0.0.5" from freebsd box and cisco-s
   and it shows that freebsd does not respond to this.
   May be it's the way it was designed in mind, but analyzing
   cisco and zebra's log I see that suddenly freebsd box is
   out of group and does not receive OSPF hello's after 2-3 minutes
   of running. May be the kernel code that processes incoming
    multicast packets
   somehow "forgets" about being in group? I don't believe it's the
   cisco's fault (both IOS's 11 and 12) ;)  And the worth part of it
   that running ospfd successfuly depends on the box I use. On some
   segments it works, on some - does not.

   Where am I wrong and being lame?

   Thanks for any helpful ideas in advance.
