Mobile IP Configuration Examples

Monitoring and Maintaining HA Redundancy

To monitor and maintain HA redundancy, use the following commands in EXEC mode, as needed:

Command	Purpose
Router# debug ip mobile standby	Displays debug messages for Mobile IP
	redundancy activities.
Router# show ip mobile globals	Displays the global home address if configured.
	For each Mobile IP standby group, displays the
	home agent address supported.
Router# show ip mobile binding [home-agent address summary]	Displays mobility bindings with specific home
	agent address.

Home Agent Configuration Example

In the following example, the home agent has five mobile hosts on interface Ethernet1 (network 11.0.0.0) and ten on virtual network 10.0.0.0. There are two mobile node groups. Each mobile host has one security association. The home agent has an access list to disable roaming capability by mobile host

11.0.0.5.The 11.0.0.0 group has a lifetime of 1 hour (3600 seconds). The 10.0.0.0 group cannot roam in areas where the network is 13.0.0.0.

!

!Define which hosts are permitted to roam

ip mobile home-agent broadcast roam-access 1

!Define a virtual network

ip mobile virtual-network 10.0.0.0 255.0.0.0

!

! Define which hosts are on the virtual network, and the care-of access list

ip mobile host 10.0.0.1 10.0.0.10 virtual-network 10.0.0.0 255.0.0.0 care-of-access 2
