ospf stub & NSSA
Hi guys,
I am not 100% comfortable distinguishing btw. when to use nssa or stub
Assuming R1 connection to the rest of the ospf domain is through R3. Since R1 does not need specific routing information to the rest of the network, it just needs to receive only a default route.
***
These two solutions seems to be doing the same thing for me
***
*Solution 1*
R3#
router ospf 1
area 5 nssa no-summary
R1#
area 5 nssa.
*Sol.2*
R3#
area 5 stub no-summary
R1#
area 5 stub
***
My question is when can you categorically use nssa over stub, or vice-versa?
Thanks
Uyota
