Configuring Mobile IP

Mobile IP HA Redundancy Configuration Task List

•Enabling HSRP (Required)

•Enabling HA Redundancy for a Physical Network (Required)

Depending on your network configuration, perform one of the optional tasks described in the following sections:

•Enabling HA Redundancy for a Physical Network (Optional)

•Enabling HA Redundancy for a Virtual Network Using One Physical Network (Optional)

•Enabling HA Redundancy for a Virtual Network Using Multiple Physical Networks (Optional)

•Enabling HA Redundancy for Multiple Virtual Networks Using One Physical Network (Optional)

•Enabling HA Redundancy for Multiple Virtual Networks Using Multiple Physical Networks (Optional)

•Verifying HA Redundancy (Optional)

Enabling Mobile IP

To enable Mobile IP on the router, use the following command in global configuration mode:

Command	Purpose
Router(config)# router mobile	Enables Mobile IP on the router.

Enabling HSRP

To enable HSRP on an interface, use the following command in interface configuration mode:

Command	Purpose
Router (config-if)# standby [group-number] ip ip-address	Enables HSRP.

Configuring HSRP Group Attributes

To configure HSRP group attributes that affect how the local router participates in HSRP, use either of the following commands in interface configuration mode:

Command	Purpose
Router(config-if)# standby [group-number] priority priority	Sets the Hot Standby priority used in choosing the
[preempt [delay [minimum sync] delay]]	active router. By default, the router that comes up
or	later becomes standby. When one router is
	designated as an active HA, the priority is set
Router(config-if)# standby [group-number] [priority priority]	highest in the HSRP group and the preemption is
	set. Configure the preempt delay sync command
preempt [delay [minimum sync] delay]
	so that all bindings will be downloaded to the
	router before it takes the active role. The router
	becomes active when all bindings are downloaded
	or when the timer expires, whichever comes first.
