Controlling the Mobile IP Lifetime on a Per-Domain Basis
The system does not support the configuration of the MIP lifetime timer on per- domain (context) basis. However, a
domain-wide lifetime timer can be achieved by configuring the idle-timeout attribute for the default subscriber for each
domain.

domain.
Important:
Mobile IP lifetime settings can be controlled on a per-domain basis only in deployments for which
the idle timeout attribute for individual subscriber profiles is not used during operation.
In this configuration, the value of the registration lifetime sent by the system in Agent Advertisements is selected by
comparing the configured FA Agent Advertisement lifetime setting, and the idle and/or absolute timeout settings
configured for the domain’s default subscriber. If the value of the idle and/or absolute timeout parameter is less than the
Agent Advertisement lifetime, then the system provides a registration lifetime equal to 5 seconds less than the lowest
timer value.

If the idle timeout attribute is configured in individual subscriber profiles, per-domain lifetime control is not possible. In
this case, the registration lifetime configured for the FA must be the lower of the two values.
