VERIFYING ROUTING PROTOCOLS

IP Routing Operational?

Below is an example of a configuration used to verify IP routing over a WAN interface. It uses IP addresses specific to the example. Substitute the IP addresses of your network when you perform the verification steps. It also uses the “ping” command. The “ping” command sends a packet to a specified host, waits for a response, and reports success or failure. Substitute the equivalent command on your IP host.

CSX5500 192.100.1.1

ISDN

100.0.0.1

100.0.0.0

Host B

192.100.1.3

Host A

100.0.0.2

1.Determine if a remote IP host can access the WAN interface of the CyberSWITCH over the WAN connection. On the remote IP host, type:

ping 192.100.1.1 <return>

If the remote IP host successfully pings to the CyberSWITCH, continue with step 3.

2.If the remote IP host CANNOT ping to the system, try the following:

a.Verify that the WAN connection is up. Use the mc console command to display the Connection Monitor display. Check for the connection. If the connection is up, continue with the next step.

If the connection is NOT up, refer to the section titled Remote Device Connectivity.

b.Verify that the WAN interface is properly initialized. Use the ipnetif command (Manage Mode) to check for the proper WAN interface. If it exists, continue with the next step.

If the proper WAN interface does not exist, make corrections to the system configuration using CFGEDIT.

c.Check that the IP address configured in the Device list for the IP Host device matches the address configured on the IP Host device. Make corrections to the CyberSWITCH’s configuration (using the iproute change Manage Mode command), or to the IP Host’s configuration, as required.

3.Determine if a remote IP host can access the LAN interface of the CyberSWITCH over the WAN connection. On the remote IP host type:

ping 100.0.0.1 <return>

If the remote IP host successfully pings to the CyberSWITCH, then continue with the step 5.
