To all:
Please help.
I have a connections(router to router) over frame relay and I configured OSPF protocols. But when I try the command "show ip ospf neighbor", there is no output or no connections found. Is that possible that using frame relay connections, the LSA's didn't send?
TIA
Below are examples for clarifications:
Router0#sho run

Are you sure you want a wildcard mask of 0.0.0.255 on a /30 point-to-point?
Try the interface's IP address with a wildcard of 0.0.0.0.
Just a shot in the dark ...

I believe that the problem is in your frame relay map statements. On router0 you have:
ip address 192.176.1.17 255.255.255.252
frame-relay map ip 192.176.1.17 101 broadcast cisco
but why does it point to its own address? I suggest that you change it to
frame-relay map ip 192.176.1.18 101 broadcast cisco
and on router5 you have:
ip address 192.176.1.18 255.255.255.252
frame-relay map ip 192.176.1.18 100 broadcast cisco
and I suggest that you change it to
frame-relay map ip 192.176.1.17 100 broadcast cisco

Thanks Rick and Scott for the additional info. I try this first. BTY, I passed CCNA 640-801 last year of October with the help of this forum..

Hi Rick,
Your suggestion was invalid because when I try to change the map the output is just like this:
Router0(config-if)#frame-relay map ip 192.176.1.18 101 broadcast cisco
%Address already in map
Router0(config-if)#
same output at Router5.
But when I ping from Router0 to Router5, it is OK and by itself. But when I try to ping from the host connected to Router0 going out to Router5, the problem exist..Is it possible on OSPF area 0 problem?

Did you remove the existing frame relay map before you attempted to configure the new one?
Perhaps some additional information would help us to figure out what the problem is. Would you post the output from these commands:
show frame-relay map
show ip ospf interface
show cdp neighbor detail

Martee,
The default ospf network type in this case is "non-broadcast", which requires the neighbor statement to be configured for the session to come up. Try configuring "ip ospf network broadcast" under the interface on each side. You could also set the network type as point to point as you only have these two neighbors.

1. When issuing a frame relay map this is the local ip address to map to thr remote DLCI
2. Under each interface type the command ip ospf network point-to-point
3. Also if you are running loopbacks for router id then add the ip oapf network type point-to-point over lopback interfaces
After perfroming the following test by issuing ther following commands
sh ip ospf neigh - shows ospf directly connected neighbor
sh ip ospf interface- ospf interface info
sh ip ospf data - ospf lsa database
