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 date;sudo vtysh -c 'sh ip osp int gre1' Thu Oct 23 10:51:51 EDT 2008 gre1 is up ifindex 10, MTU 1412 bytes, BW 0 Kbit Internet Address 10.255.13.30/30, Peer 10.255.13.29, Area 0.0.0.2 MTU mismatch detection:disabled Router ID 10.254.150.1, Network Type POINTOPOINT, Cost: 10 Transmit Delay is 1 sec, State Point-To-Point, Priority 0 No designated router on this network No backup designated router on this network Multicast group memberships: OSPFAllRouters Timer intervals configured, Hello 10s, Dead 40s, Wait 40s, Retransmit 5 Hello due in 3.069s Neighbor Count is 1, Adjacent neighbor count is 0 >From log file: 2008/10/23 10:51:54 OSPF: *** sendmsg in ospf_write failed to 224.0.0.5, id 0, off 0, len 68, interface gre1, mtu 1412: Network is down Anyone have an idea on what is causing this? I also have this problem with 0.99.6
