To verify that IP routing is properly operational over a WAN Remote LAN interface, a remote IP
Host must be operational and connected to the remote LAN. The remote bridge device must be
operational and available to initiate connections. Also, a local IP host must be connected to the local
LAN port on the CyberSWITCH.
Below is an example of a configuration used to verify IP routing over a WAN Remote LAN
interface. It uses IP addresses specific to the example. Substitute the IP addresses of your network
when you perform the IP routing 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.
The steps to verify the operation of IP routing over a WAN Remote LAN interface are:
1.
Determine if a remote IP host can access the WAN Remote LAN 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, then continue with the next step.
If the remote IP host CANNOT ping to the CyberSWITCH, refer to
Remote LAN Interface Connection
of the Problem Diagnosis chapter.
2.
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 next step.
If the remote IP host CANNOT ping to the CyberSWITCH, refer to
Remote LAN Interface Connection
of the Problem Diagnosis chapter.
3.
Determine if a remote IP host can access the local IP host through the CyberSWITCH over the
WAN connection. On the remote IP host type:
ping 100.0.0.2
<return>
100.0.0.1
100.0.0.0
Host A
100.0.0.2
Host B
