All the configuration specific to Registration Revocation is performed on the Home Agent, with the exception of the FAHA security association. After a security association is configured, revocation is configured with the following command:
ip mobile home-agent revocation [timeout number] [retransmit number]
The optional timeout and retransmit parameters control how long the Home Agent must wait for a reply to the revocation message and how many times the revocation message is to be retransmitted.
Some versions of IOS support a prestandard version of revocation that is referred to as bindupdate. You should use the standards-based revocation wherever possible. This Binding Update is not related to the Binding Update functionality in Home Agent Redundancy.
