Hi,
I seem to be having problems pinging the directly connected router.
My interfaces at both routers are UP/UP. But cannot ping the other end.When I ping from my Node to the CPE router I get U.U.U.U. and when I ping the node from the CPE I get .....
Here is what I have configured at node
sh int s2/1/0
Serial2/1/0 is up, line protocol is up
Hardware is cyBus E3 Serial
Internet address is X.X.X.X/30
MTU 4470 bytes, BW 16384 Kbit, DLY 200 usec, rely 255/255, load 1/255

On the CPE router this is what I have got

Although you have interface ' up/up ' you do not have a healthy DSU/line condition. ie CA is down, TA is down on your interface ;
LC=up CA=down TM=down LB=down TA=down LA=down
another clue to the line problem or misconfiguration is the vast number of errors clocking up at the CPE end;
1181777058 input errors, 152531911 CRC, 0 frame,
DCE Available (CA) indicates that the DCE data service unit (DSU) is prepared to send and receive data to and from the DTE. DTE Available (TA) indicates the DTE is prepared to send and receive data to and from the DCE (DSU). Data transmission can begin only after both CA and TA have been asserted.
Loopback Circuit C (LC) is software-controlled to request a loopback by the DCE to the DTE. The loopbacks LA and LB enable the system diagnostics to verify the links between the DTE and DCE. LA and LB are sent from the DTE to request loopbacks in the DSU. LC is sent by the DCE (DSU) to request loopbacks from the DTE; by default, LC is inhibited by software.
best of luck !
