This
chapter contains a diagnostic map to help you solve problems that might occur
when you use the Mobile IPv6 kit.
Use this chapter, along with the appropriate Compaq
documentation, to solve as many problems as possible at your level.
6.1 Using the Diagnostic Map
Mobile IPv6 problems can occur for a number of reasons. The diagnostic map in this chapter should help you isolate the problem. The following figure explains how to use the diagnostic map:
After you isolate the problem, the map refers you to other sections for instructions on using the various problem-solving tools and utilities. The map also refers you to other manuals for complete diagnostic information for particular devices and software products.
You could experience problems that are not documented in this manual
when you use the Mobile IPv6 network software with other products.
See the
documentation for the other products for additional information.
6.2 Getting Started
Before you start problem solving, ensure that communications hardware is ready for use. Verify the following:
The system's physical connections are properly installed. See the documentation for your system and communications hardware device.
Event logging is enabled to monitor network events. See the System Administration manual for information on starting event logging and for descriptions of event messages.
Also check the product release notes for up-to-date information on known problems.
You should also be familiar with the following terms before you start problem solving:
An on-link node is attached to the same subnetwork as your system. This subnetwork can be a LAN, a serial connection running PPP, or an IPv6 over IPv4 configured tunnel. There are no IPv6 routers between your system and the on-link node. For the configured tunnel, the on-link node is the node at the destination end of the tunnel.
An off-link node is not attached to the same subnetwork as your system. There is at least one IPv6 router between your system and the off-link node.
You should also be sure that your system, whether IPv6 host or IPv6
router is operating correctly.
See the
Network Administration: Connections
manual for information
about solving network and IPv6 problems.
6.3 Solving Mobile IPv6 Problems

Verify that the Mobile IPv6 kit is installed. Enter the following commands: # cd /usr/kits/mobileipv6 # ./installmobileipv6demo
The following message should appear immediately after the Installation menu selections: *** Kit version nnn, draft xx, is currently installed *** *** This system is currently acting as a ??? ***
If the kit is not installed, install it by choosing option 1 from the menu. See Section 3.1 for more information. |

Verify that both the home agent and correspondent node have a binding for the mobile node by issuing the following command on both systems: # netstat -b | grep hostname
If no entry exists for the mobile node, complete the following steps:
