1. Everyone in an area must agree on the stub flag in the updates, and
everyone must agree on the database. So yes, configure nssa on everyone.
2. Virtual links are necessary to make that happen. Virtual links are not
allowed in stub areas (although your router would tell you this). Are there
any alternatives you can think of if that's a necessary design? (real life,
that's a bad idea)

Subject: ospf nssa qustion
Hi Group,
If i have this network
r1------r2-------r3------r4
r1 and r2: ospf area 0
r2 and r3: ospf nssa, area 23
r3 and r4: ripv2
1) do i configure "nssa" commands on both r2 and r3?
i find that it works even when i just do it at r2.
I think it is need on both r2 and r3, stub flags
have to agree
2) if i create a area3 in r3, put a loopback interface
into area 3, r2 doesnt get that route
that means can i add another ospf area on the edge of
nssa area, r3 ? that might be the reason why r2 cannot
receive the route when i do that?
Appreciate any inputs
Thanks
Lim
