seems to work fine for me... aren't you sure that the problem is not in the ethernet card ? I have heard that some cards have problems in the programming of the multicast filter. Second thing, you can try to set sysctl -w net.inet.icmp.bmcastecho=1 to see if the box responds to the multicast address. For sure this influences how the box responds to pings to tue subnet broadcast address. cheers luigi On Sat, Apr 13, 2002 at 05:31:42PM +0300, Oles Hnatkevych wrote: > 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.
