RE: OSPF PROBLEM

I'll take a stab at this.

You don't need the virtual link, because you are connecting directly to
area 33 from area 0. You would use "area 33 virtual-link xx.xx.xx.xx"
if you had to CROSS area 33 to join a remote area with area 0, or to
join a part of area 0 that was cut off from the rest of area 0.

Just remove the virtual-link statement and see what happens. And remove
it from the other side of the link in question, too.

Maybe I'm missing something. This seems too simple. Is there some
other area you have not told us about?

Best regards,
Thomas Larus

Subject: OSPF PROBLEM

I've got a Frame Relay network running OSPF. I have the Frame-relay all
in
area 0, r1 is connected to R2, R3, and R4.
R4 is connected to R5 area 33 via a serial ptp connection. The routes
from
area 0 are getting into area 33 but the routes from area 33 are not
making it
into area 0. There is no authentication happening. Here is the configs
for
Router 4 (the problem router)

interface Serial0
 ip address 135.3.2.70 255.255.255.252
 no ip directed-broadcast
 ip ospf interface-retry 0

 no fair-queue
 clockrate 64000
