OSPF ADJ Problem

Bugs
1

Good afternoon. I am having problems getting vyOS to talk OSPF with a pfsense firewall which is essentially of course Quagga as the routing daemon.

I am trying to determine if this is a vyOS problem or a Quagga problem, but I decided to start here since I don’t have problems with adjacencies between Quagga and say IOS or JunOS.

Here is the Quagga config:

v-edge-01.emrlab.info# sh run

Current configuration:
!
password BlackD3ath6
log syslog

!
interface em0
!
interface em1
!
interface em2
!
interface em2_vlan200

end

Here is the VyOS config:

}
}
table 1 {
route 0.0.0.0/0 {
next-hop 172.16.254.10 {
}
}
}
}
}

LOGS:

vyos@VYOS-01:~$ sh log tail | grep prefix

Any ideas here? I will certainly provide more information if it helps point me in the right direction. Thanks in advance.

I’ve encountered the same problem using 1.1.5.
I did quick rollback to vyatta 6.5R1 which is my main production version since 2013 cause I had no time to test and solve the issue. Same configuration commands, same hypervisor, same environment, different version. Problem does not occur.

I also have 1.0.4 hydrogen in production, configured in the same meshed environment using ospf - the problem also does not occur.
