Can you post your config's and show the output of "show ip ospf neighbor"
for each of the routers?

Tim,,,
I just have a trunk between R2 and R3, PVST doesn4t have a problem.
Checking this link
http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a00800949f7
.shtml#trouble_full_adj
I make a redistribution conected in R4 with a route-map matching loopback 0.
It says that if the router have a the ext route in the database and the
forward address is 0.0.0.0,,, OPEN A TACA CASE.
But the problem is R1 also doesn4t receive the subnet /30 between R3 and R4
and this route is intra area, because all routers are un area 0.
I think it could be a soft bug.
Rgds,,,

Sergio,
I'm just guessing but I suspect this problem might have something to do with
the fact you have a trunk between R2 and R3 instead of an etherchannel.
By having a trunk, spanning tree will block all but one of the physical
links.
Without more detail, I can't be certain but that's my thinking.
HTH, Tim

Subject: PROBLEM WITH " Adv Router is not-reachable " OSPF DATABASE ROUTER
Hi Group,,,
I have the following problem: SOME OSPF ROUTES ARE IN THE DATABASE BUT NOT
IN THE IP ROUTING TABLE
Topology:
R1----L3-----R2------TRK/Dot1q--------R3-----L3-----R4
Each router has a int loopback 0, this is the router ID.
R2 and R3 run OSPF in four SVI. All routers are in AREA 0.
The problem is that R1 and R2 have the R4 IP Loopback 0(216.230.136.238) in
the database but not in the IP Routing table. R3 has the R4 IP Loopback 0
(216.230.136.238) in both. Also the subnet between R3 and R4 (/30) isn4t in
the routing table.
All routers have the same configuration,,,, Also R2, R3 and R4 has the
Loopbacks of R1.
I verified this document, but It doesn4t have the solution.
