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 do the following:
1. Make sure the upstream router’s interface to the ASN is enabled.
2. Make sure BOOTP is enabled on the circuit connecting the ASN to the
upstream router.
3. Make sure the upstream router’s link modules and drivers are loaded.
4. Make sure the upstream router’s IP protocol is enabled.
5. Make sure the upstream router’s BOOTP protocol is enabled.
6. Make sure the BOOTP Relay Agent Forwarding Table associated with
the upstream router shows a valid IP address that is configured on the IP
router.
7. Make sure the input IP address is correct.
8. If you are using EZ-Install over a Frame Relay permanent virtual circuit
(PVC) in group access mode, make sure the upstream router’s BOOTP
Client Interface table is configured properly.
Router Fails to Netboot
When you use the default (EZ-Install) setting for getting the IP address or when
you use the
ifconfig command, and the router fails to receive the configuration file
or image, make sure that all cables between the router and the BOOTP server are
firmly connected.
If you have not isolated the problem to a specific interface, retrieve the number of
BOOTP packets forwarded and dropped from all routers between the router and
the BOOTP server. Refer to “Displaying the Number of Packets Forwarded and
Dropped” later in this appendix.
Then refer to the instructions in the following sections, or in the section that
applies to your problem, until you find and correct the problem:
• “Upstream Router Not Receiving BOOTP Requests”
• “Router Not Sending BOOTP Responses”
• “BOOTP Server Not Sending BOOTP Responses”
