I am trying to set up Quagga ospfd on two hosts connected by an OpenVPN link. These hosts have VPN IPs 10.31.0.1 and 10.31.0.13. ospfd config is pretty simple:

hostname bizon
password xxxxxxxxx
enable password xxxxxxxxx
!
log file /var/log/quagga/ospfd.log
!
interface lo
!
interface tun0
ip ospf network point-to-point
ip ospf mtu-ignore
ip ospf cost 10
interface tun1
ip ospf network point-to-point
ip ospf mtu-ignore
ip ospf cost 10
interface tun2
ip ospf network point-to-point
ip ospf mtu-ignore
ip ospf cost 10
!
router ospf
ospf router-id 10.31.0.1
network 10.31.0.0/16 area 0.0.0.0
network 10.119.2.0/24 area 0.0.0.0
redistribute connected
area 0.0.0.0 range 10.0.0.0/8
!
line vty
!
debug ospf event
debug ospf packet all

I am getting the following error in the ospfd.log (the log is from 10.31.0.13):

2012/10/05 01:25:28 OSPF: Packet from [10.31.0.1] received on link tun1 but no ospf_interface

I'm not sure what to do next. I have set up ospfd over OpenVPN several times but I used Debian and I am on CentOS 6 now. Quagga version is 0.99.15. Should I try to get more recent version?
