[c-nsp] Prefer NSSA summary route than backbone route in OSPF

More specific route always wins.
As long as router has more specific route, /32 in your case it will use it.

Hi,


There is a subnet numbered 10.101.172.0/27, the subnet
is directly connected to OSPF area 0. Now, a NSSA area
108 is set up to host some key service, which
previously located in 10.101.172.0/27. 

We've set up both NSSA area configuration & server IP
address in it. In order to maintein unique user
interface, we hope to advertise 10.101.172.16/32,
10.101.172.17/32 from area 108 to  area 0. Any traffic
destined to 10.101.172.17/32 & 10.101.172.16/32 should
be routed to area 108 but not to backbone subnet
10.101.172.0/27. 

Can I achive it? If yes, how can I set up router
configuration?

thanks in advnace.

Joe
