HA Redundancy for a Virtual Network Using One Physical Network Example
This section presents two configuration examples:
The mobile node and home agent are on different subnets.
The mobile node and home agent are on the same subnet.
Mobile Node and Home Agent on Different Subnets
HA1 and HA2 share responsibility for providing home agent service for mobile nodes on virtual network
20.0.0.0. The home agents are connected on only one physical network.
The standby group name is SanJoseHA and the HSRP group address is 1.0.0.10. Mobile IP is configured
to use the SanJoseHA standby group to provide home agent redundancy. Thus, HSRP allows the home
agent to receive packets destined to 1.0.0.10.
This configuration differs from the physical network example in that a global HA address must be
specified to support virtual networks. This address is returned in registration replies to the mobile node.
HA1 Configuration
interface ethernet0
ip address 1.0.0.1 255.0.0.0
standby ip 1.0.0.10

ip mobile virtual-network 20.0.0.0 255.0.0.0
