7.12 OSPF Configuration Examples

A simple example, with MD5 authentication enabled:

!
interface bge0
 ip ospf authentication message-digest
 ip ospf message-digest-key 1 md5 ABCDEFGHIJK
!
router ospf
 network 192.168.0.0/16 area 0.0.0.1
 area 0.0.0.1 authentication message-digest

An ABR router, with MD5 authentication and performing summarisationof networks between the areas:

!
password ABCDEF
log file /var/log/quagga/ospfd.log
service advanced-vty
!
interface eth0
 ip ospf authentication message-digest
 ip ospf message-digest-key 1 md5 ABCDEFGHIJK
!
interface ppp0
!
interface br0
 ip ospf authentication message-digest
 ip ospf message-digest-key 2 md5 XYZ12345
!
router ospf
 ospf router-id 192.168.0.1
 redistribute connected
 passive interface ppp0
 network 192.168.0.0/24 area 0.0.0.0
 network 10.0.0.0/16 area 0.0.0.0
 network 192.168.1.0/24 area 0.0.0.1
 area 0.0.0.0 authentication message-digest
 area 0.0.0.0 range 10.0.0.0/16
 area 0.0.0.0 range 192.168.0.0/24
 area 0.0.0.1 authentication message-digest
 area 0.0.0.1 range 10.2.0.0/16
!

A Traffic Engineering configuration, with Inter-ASv2 support.

- First, the ’zebra.conf’ part:

hostname HOSTNAME
password PASSWORD
log file /var/log/zebra.log
!
interface eth0
 ip address 198.168.1.1/24
 mpls-te on
 mpls-te link metric 10
 mpls-te link max-bw 1.25e+06
 mpls-te link max-rsv-bw 1.25e+06
 mpls-te link unrsv-bw 0 1.25e+06
 mpls-te link unrsv-bw 1 1.25e+06
 mpls-te link unrsv-bw 2 1.25e+06
 mpls-te link unrsv-bw 3 1.25e+06
 mpls-te link unrsv-bw 4 1.25e+06
 mpls-te link unrsv-bw 5 1.25e+06
 mpls-te link unrsv-bw 6 1.25e+06
 mpls-te link unrsv-bw 7 1.25e+06
 mpls-te link rsc-clsclr 0xab
!
interface eth1
 ip address 192.168.2.1/24
 mpls-te on
 mpls-te link metric 10
 mpls-te link max-bw 1.25e+06
 mpls-te link max-rsv-bw 1.25e+06
 mpls-te link unrsv-bw 0 1.25e+06
 mpls-te link unrsv-bw 1 1.25e+06
 mpls-te link unrsv-bw 2 1.25e+06
 mpls-te link unrsv-bw 3 1.25e+06
 mpls-te link unrsv-bw 4 1.25e+06
 mpls-te link unrsv-bw 5 1.25e+06
 mpls-te link unrsv-bw 6 1.25e+06
 mpls-te link unrsv-bw 7 1.25e+06
 mpls-te link rsc-clsclr 0xab
 mpls-te neighbor 192.168.2.2 as 65000

- Then the ’ospfd.conf’ itself:

hostname HOSTNAME
password PASSWORD
log file /var/log/ospfd.log
!
!
interface eth0
 ip ospf hello-interval 60
 ip ospf dead-interval 240
!
interface eth1
 ip ospf hello-interval 60
 ip ospf dead-interval 240
!
!
router ospf
 ospf router-id 192.168.1.1
 network 192.168.0.0/16 area 1
 ospf opaque-lsa
  mpls-te
  mpls-te router-address 192.168.1.1
  mpls-te inter-as area 1
!
line vty

A router information example with PCE advsertisement:

!
router ospf
 ospf router-id 192.168.1.1
 network 192.168.0.0/16 area 1
 capability opaque
  mpls-te
  mpls-te router-address 192.168.1.1
 router-info area 0.0.0.1
  pce address 192.168.1.1
  pce flag 0x80
  pce domain as 65400
  pce neighbor as 65500
  pce neighbor as 65200
  pce scope 0x80
!
