failover ]
failover ]

Feature is disabled by default.

aaa-override mn-supplied-ha-addr
Enables the system to override the mobile node supplied HA IP address with the AAA provided HA address.
allow-failover
Enables/disables a failover retry for dynamic HA assignment from the AAA server.
Usage
Use this command to override the mobile node supplied HA IP address with the AAA supplied HA address.
Use this command to enable or disable the failover feature that allows the system to receive and use a newer
HA address from the AAA server in cases where the original HA address is not responding.
A AAA server may assign different HA addresses each time a retransmitted MIP RRQ is authenticated during
the MIP session setup. When this configuration is enabled, if the FA gets a new HA address from AAA
during setup, it discards the previous HA address and start using the new address. This allows the FA session
to connect to an available HA during setup.
