I ran into this problem myself. The "match ip next-hop" matches the next
hop field in routing updates only. You need to define an access list for
your route map that will match on destination IP addresses and set the next
hop accordingly.
As for OSPF, you can either change your network type to broadcast or you can
use the "neighbor" statement under OSPF to explicitly define an OSPF
neighbor across the frame relay cloud.

You need to configure ip ospf network point-to-multipoint on R1's s0.2
(multi) , on R3 and R5.
Make sure you use broadcast on map statements.
Remember OSPF and NBMA:
OSPF Net type Hello/Dead Election
Broad 10/40 DR/BDR
P-P 10/40 No Election
Non-Broad 30/120 DR/BDR
P-MP 30/120 No Election

Subject: Policy Routing and OSPF Adjacencies
I am working on CCIE Bootcamp lab #3 (Those of you with copies please refer
to the first diagram on lab 3).
I have four routers (1,3,4,5), three are connected via a partial-mesh frame
network. Routers 3 and 5 are connected via PVCs to router 1, while router 4
is connected to router 3 via a direct serial cable.
The requirements of the lab explicitly forbid the use of multiple frame-map
statements to overcome the partial-mesh issues. I have used a route-map that
forces traffic from router 3 to router 5 to be forced through router 1's
frame interface. However, when the policy is applied to local packets (ip
local policy...) router 3 fails to form an adjacency with router 4 (Sits in
INIT state). I am however able to ping router 4 from router 3. If I remove
the local policy, the routers form an adjacency.
Has anyone else seen this?
