Configuring Mobile IP

Mobile IP HA Redundancy Configuration Task List

	Command	Purpose
Step 4
	Router(config)# ip mobile home-agent address address	Defines the global home agent address for virtual
		networks. In this configuration, the address is the
		loopback interface address. Enter this command if
		the mobile node and home agent are on different
		subnets.
	or	or
	Router(config)# ip mobile home-agent	Enables and controls home agent services to the
		router. Enter this command if the mobile node and
		home agent are on the same subnet.
Step 5
	Router(config)# ip mobile virtual-network net mask	Defines the virtual networks. Repeat this step for
	[address address]	each virtual network. If the mobile node and home
		agent are on the same subnet, use the [address
		address] option.
Step 6
	Router(config)# ip mobile home-agent standby	Configures the home agent for redundancy using
	hsrp-group-name1 [[virtual-network]address address]	the HSRP group 1 to support virtual networks.
Step 7
	Router(config)# ip mobile home-agent standby	Configures the home agent for redundancy using
	hsrp-group-name2 [[virtual-network]address address]	the HSRP group 2 to support virtual networks.
Step 8
	Router(config)# ip mobile secure home-agent address	Sets up the home agent security association
	spi spi key hex string	between peer routers. If configured on the active
		HA, the IP address address argument is that of the
		standby HA. If configured on the standby HA, the
		IP address address argument is that of the active
		router. Note that a security association needs to be
		set up between all HAs in the standby group.

Verifying HA Redundancy

To verify that the Mobile IP Home Agent Redundancy feature is configured correctly on the router, perform the following steps:

Step 1 Enter the show ip mobile globals EXEC command.

Step 2 Examine global information for mobile agents.

Step 3 Enter the show ip mobile binding [home-agent address summary] EXEC command.

Step 4 Examine the mobility bindings associated with a home agent address.

Step 5 Enter the show standby EXEC command.

Step 6 Examine information associated with the HSRP group.
