Thanks. We'll let you know when a new response is added.

In its most simplistic form ….

switch(config) ip routing

switch(config) router ospf (process-ID)
switch(config-router)#log-adjacency-changes

I am not going to go into anymore detail because OSPF can be configured many different ways depending on the requirements. But in addition to the two commands above, you will need to specify networks and area’s such as

network 1..1.1.0 0.0.0.3 area 0

Also you might want to look into creating loopack intefaces and making then the router ID for OSPF, since loopback intefaces never go down

int lo0
ip address 1.1.1.1 255.255.255.252

router ospf 1
router-id 1.1.1.1

    You can just config like this:
    R1#conf t 
    R1(config)#router ospf 110  
    R1(config-router)#network 12.1.1.1 0.0.0.0 area 0 
    R1(config-router)#network 1.1.1.1 0.0.0.0 area 0
