Hi Debbie,
I think the problem here is that you need a virtual link between R5 and R3
BUT you need to be aware that you form virtual links using RouterID's, not
necessarily router loopbacks!
can I suggest you try and form the virtual link, by doing the following.
1. Make the routerID of router3 the serial(FR) interface
2. Make the routerID of Router4 the ethernet interface.
you should be able to ping R3 from R5 and vica versa (router IDs)
it's then simply a matter of configureing the virtual link between these
routers
please let me know how you get on!
cheers
Adam

Subject: Ospf stub and NSSA problem
I'm working on a lab and need alittle help.....
Here's the diagram:
------- ------
| R1 |------------ | R3 |
------- -------
|
|
-------
| R2 |
-------
|
|
------
| R5 |
-------
* There is frame-relay, fully meshed between R1, R2 & R3., R5 is connected
via ethernet.
* R1 (all interfaces), area 1
* R2 (loopback2, s0/0.1and s0/0.2) - area 1
* R3 (s0/0.1 & s0/0.2) are in OSPF area 1
* Area 1 is an NSSA.
* R3 (interfaces L0, L1, & L2 are area 0), e0/0 is area 3.
* R5 (Interfaces e0/0, L0) area Area 2.
* Area 2 is a stub network.
I don't see routes in R3 to R5, except for the directly connected. And
vice versa from R5 to R3. In addition, on R5 I have formed a neighbor
relationship, but have no routing table, except for the directly
connected.
I tried setting up a virtual link through Area 1, but it will not because
Area 1 is an NSSA.
I don't know what I'm missing.
Thanks for any assistance
Debbie
