Enabling HA Redundancy for Multiple Virtual Networks Using One Physical Network

To enable HA redundancy for multiple virtual networks using one physical network, use the following commands beginning in interface configuration mode:

	Command	Purpose
Step 1
	Router(config-if)# standby [group-number] ip	Enables the HSRP.
	ip-address
Step 2
	Router(config-if)# standby name hsrp-group-name	Sets the name of the standby group.
Step 3
	Router(config)# ip mobile home-agent address address	Defines a global home agent address. In this
		configuration, the address is the HSRP group
		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 4
	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 5
	Router(config)# ip mobile home-agent standby	Configures the home agent for redundancy using
	hsrp-group-name [[virtual-network]address address]	the HSRP group to support virtual networks.
Step 6
	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.

Enabling HA Redundancy for Multiple Virtual Networks Using Multiple Physical Networks

To enable HA redundancy for multiple virtual networks using multiple physical networks, use the following commands beginning in interface configuration mode:

	Command	Purpose
Step 1
	Router (config-if)# standby [group-number] ip	Enables the HSRP.
	ip-address
Step 2
	Router(config-if)# standby name hsrp-group-name1	Sets the name of the standby HSRP group 1.
Step 3
	Router(config-if)# standby name hsrp-group-name2	Sets the name of the standby HSRP group 2.
