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 10.2.1.0/24 area 0.0.0.0
 area 0.0.0.0 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

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)
