Configuring Remote Access for AN and Passport ARN Routers
B-2 308614-14.20 Rev 00
Router Fails to Get IP Address
If a message at the AN/ANH or ARN router console indicates that the router
failed to get an IP address from the upstream router, or that the upstream router is
unable to receive BootP requests, ensure that the network cable between the AN/
ANH or ARN router’s synchronous port and the upstream router is firmly
connected. Then, refer to the instructions in one of the following sections to find
and correct the problem:
•Upstream Router Not Receiving BootP Requests
•Upstream Router Not Sending BootP Responses
If you follow the instructions in these sections and cannot find and correct the
problem, contact the Nortel Networks Technical Solutions Center.
Upstream Router Not Receiving BootP Requests
If the upstream router is not receiving BootP requests, use the getcfg command to
display the router parameters and the bconfig and ifconfig commands to correct
them, if necessary. For instructions, see “Displaying Parameter Settings” on
page B-10 and “Debugging the BootP Server” on pageB-12.
Upstream Router Not Sending BootP Responses
If the upstream router is receiving BootP requests but is failing to send BootP
responses, use Site Manager to verify the following:
•The upstream router’s interface to the AN/ANH or ARN router is enabled.
•BootP is enabled on the circuit connecting the AN/ANH or ARN router to the
upstream router.
•The upstream router’s link modules and drivers are loaded.
•IP is enabled on the upstream router.
•BootP is enabled on the upstream router.
•The BootP relay agent forwarding table associated with the upstream router
shows an IP address that is configured on the IP router.
•The input IP address is correct.
•If you are using EZ-Install over a Frame Relay PVC in group access mode,
the upstream router’s BootP client interface table is configured properly.
