OSPF Authentication for linux server

Dear Experts,

I 'm giving a last minute task to get a Linux server firewall authenticated with the backbone network that runs using OSPF.

Server information:

 lsb_release -a
No LSB modules are available.
Distributor ID:      Debian
Description:      Debian GNU/Linux 6.0.10 (squeeze)
Release:      6.0.10
Codename:      squeeze

I have this is the quagga config file

! Zebra configuration saved from vty
!   2008/09/03 11:04:04
interface bond0
interface eth0
 description to Logix Internet
interface eth1
 description to backbone
 ip ospf message-digest-key 1 md5 Lmxxxx <-- this is correct
interface eth2
 description to Blah Internet
interface eth3
 description to DMZ
interface gre0
interface ifb0
interface ifb1
interface lo
interface teql0
interface tunl0
router ospf
 network area
 area authentication message-digest

The server that is going to be a firewall now pings the Internet not the backbone. I think is because is not authenticating.

Any help is appreciated.

Is your key number the same at both ends (both devices)?

ip ospf message-digest-key 1 md5 Lmxxxx

Not sure,

I see the entry with the key in ospf file not in zebra

How does zebra config files authenticates with the OSPF backbone network. Should I have the message-digest key in there as well?
If you use authentication you ospf for two connected interfaces
- authentication type (clear text or MD5) must match
- key number must match
- password must match (usually - worst case to detect is if there is space on the end of password " ")

For OSPF to be able to create neighbor relationship you need
- router must have router-id or ospf process won't start
- area number must match
- subnet mask must match (except for point-to-point and virtual links)
- hello and dead timers must match
- stub area flag (if there is one)
