RE: OSPF with secondary IP's

Danny,

I'm surprised that you were able to get the neighbors established. I
agree with Tim that they effectively are on uncommon subnets. I tried
several approaches unsuccessfully. What configuration did you use to
form the neighbor adjacencies?

thanks,

Tim

Thanks for all the responses, guys. I tried this in my lab and what I
found is that they will become neighbors but no routes are learned.

Negative, you'll get errors due to the fact that the router will source
the OSPF hellos (assuming you put the primary into a OSPF area) from the
primary interfaces. Much the same way you'll see "not on common subnet"
errors with EIGRP.

Hello, Group.
 
R1------R2
 
R1
ip address 1.1.1.1 255.255.255.0
ip address 2.2.2.2 255.255.255.0 secondary
 
R2
ip address 2.2.2.1 255.255.255.0
ip address 1.1.1.2 255.255.255.0 secondary
 
Both networks are under OSPF in the same area. Will the two routers
become adjacent?
 
Thanks,
Danny
