Configuring Remote Access
A-2 114084 Rev. A
Router Fails to Get IP Address
If a message at the router console indicates that the router failed to get an IP
address from the upstream router, or if the upstream router is failing to receive
BOOTP requests or respond to them, make sure that the network cable between
the router’s synchronous port and the upstream router is firmly connected. Then
refer to the instructions in one of the following sections until you find and correct
the problem:
Upstream Router Not Receiving BOOTP Requests
Upstream Router Not Sending BOOTP Responses
Contact the Bay Networks Technical Response Center if you follow the
instructions in these sections and cannot find and correct the problem.
Upstream Router Not Receiving BOOTP Requests
If the upstream router is not receiving BOOTP request messages, use the
getcfg
command to display the router parameters and the bconfig and ifconfig
commands to correct them if necessary. Refer to “Displaying Parameter Settings
and “De
bugging the BOOTP Server” later in this appendix if you need
instructions.
Upstream Router Not Sending BOOTP Responses
If the upstream router is receiving BOOTP request messages but failing to send
BOOTP responses, use Site Manager to verify the following:
The upstream router’s interface to the AN/ANH/ARN is enabled.
BOOTP is enabled on the circuit connecting the AN/ANH/ARN to the
upstream router.
The upstream router’s link modules and drivers are loaded.
The upstream router’s IP protocol is enabled.
The upstream router’s BOOTP protocol is enabled.
The BOOTP relay agent forwarding table associated with the upstream router
shows a valid IP address that is configured on the IP router.
The input IP address is correct.
