Richard's recipe for OSPF on Cisco
This recipe is simple. In this example, all the OSPF routers are on a
single "backbone" network, 192.168.0.x
The OSPF key is "dumbsecret".
- interface Ethernet0
- ip address 192.168.0.1 255.255.255.0
- ip ospf authentication-key dumbsecret
- router ospf 1
- redistribute connected subnets
- redistribute static subnets
- network 192.168.0.0 0.0.0.255 area 0
- area 0 authentication
The first redistribute statement causes your router to
announce the networks directly connected to the router's other interfaces.
The subnets modifier says that you want to announce all
networks, not just the ones exactly class A, B, or C size.
The second redistribute tells your router to announce
any static routes that you have configured. And as before,
subnets means that you don't want your subnets to
quietly disappear.
The network statement is for the network your router
will use for speaking OSPF. Note that this is unlike RIP, which needs
one for each network to announce.
Are you looking into using a Linux or BSD box as a router? Quagga
is routing protocol software that looks and acts like Cisco IOS, but runs on your
favorite operating system and is free.
