I've 2 routers conncted via MPLS IP VPN.
I try to up OSPF between it.

===========================
I don't have ospf neighboors. I tryed to select for interfsaces -
ip ospf network point-to-multipoint
or ip ospf network broadcat
but it didn't help.
I tryed to write neighboors address but get message-
GW(config)#router ospf 21
GW(config-router)#nei
GW(config-router)#neighbor 172.30.0.9
OSPF: Neighbor address does not map to an interface
---------
Why i get that message?

Just looking at this quickly I'm seeing that the serial interfaces are not on the same subnet(assuming that these routers are connected through the serial 0/0 interfaces), which is why you would get "OSPF: Neighbor address does not map to an interface"
R1
#sh ip ospf interface
Serial0/0 is up, line protocol is up
Internet Address 172.30.0.9/30, Area 1
(This /30 has two usuable IP addresses in the subnet - 172.30.0.9 and 172.30.0.10)
R2
GW#sh ip ospf int
Serial0/0 is up, line protocol is up
Internet Address 172.30.0.21/30, Area 1
(This /30 has two usuable IP addresses in the subnet - 172.30.0.21 and 172.30.0.22)
