Hi,

I am having a problem on FreeBSD 6.3-p5.

I am using gre over vpn for ospf. When I do a tcpdump on
the gre tunnel I immediately start seeing in the my ospfd log file the 
following:

2008/10/23 10:39:54 OSPF: *** sendmsg in ospf_write failed to 224.0.0.5, id 0, off 0, len 68, interface gre1, mtu 1412: Network is down
2008/10/23 10:40:04 OSPF: *** sendmsg in ospf_write failed to 224.0.0.5, id 0, off 0, len 68, interface gre1, mtu 1412: Network is down
2008/10/23 10:40:14 OSPF: *** sendmsg in ospf_write failed to 224.0.0.5, id 0, off 0, len 68, interface gre1, mtu 1412: Network is down

and I lose my ospf routes in the routing table.

If I exit tcpdump and do and ifconfig gre1 it shows it is up. And in fact in the tcpdump
I see Hello packets from the other side.
Even ospf thinks it is up

Anyone have an idea on what is causing this?

I also have this problem with 0.99.6
