Ip Routing Over A Wan Unnumbered Interface Connection - Cabletron Systems SmartSwitch 9W006 User Manual

2. Verify that the LAN interface is properly initialized. Use SFVRA-CFG (refer to
instructions) to check for the proper LAN interfaceIf the proper interface exists, then continue
with the next step.
If the proper interface does not exist, use SFVRA-CFG to make the necessary corrections.
3. Verify that the remote bridge device is initiating a call to the SmartSwitch Remote Access
Module. Since the SmartSwitch Remote Access Module LAN interface has an IP address
assigned with a different network number than the one for the remote IP Host, the remote IP
Host may need a proper route entry for the local network where the SmartSwitch Remote
Access Module is located. Make corrections to the remote IP Host configuration.
Problem:
The remote IP Host connected to a WAN RLAN interface on the SmartSwitch Remote Access
Module does not receive a ping response from the local IP Host.
Action:
1. Verify that the remote IP Host can access the LAN interface of the SmartSwitch Remote Access
Module. If it accesses the LAN interface, then continue with the next step.
If the remote Host is unable to access the LAN interface, refer to the preceding problem and
action.
2. Verify that the local IP Host has the route entry for the remote network with the SmartSwitch
Remote Access Module as the next hop. If it does, refer to
Connection in the System Verification chapter.
If the local IP Host does not have the proper route entry, make corrections to the local IP Host
configuration.

Problem:
The remote router connected to a WAN UnNumbered interface on the SmartSwitch Remote Access
Module does not receive a ping response from the SmartSwitch Remote Access Module LAN
interface.
Action:
1. Have the remote router ping itself using its LAN IP address.
2. Have the SmartSwitch Remote Access Module ping itself using its LAN IP address.
3. Have the router ping the SmartSwitch Remote Access Module. If the ping is unsuccessful:
• and no call is up, check the static route on the router
• and a call is up, check the static route on the SmartSwitch Remote Access Module (refer to
page 82
CFG).
