Default destination profiles for GRE and DVMRP are generated at system startup. The system supports only one default GRE destination profile and one default DVMRP destination profile.
The default destination profile enables the application to automatically create dynamic IP tunnels without user configuration for any virtual router, destination address, or source address.
By default, the data MDT application is disabled in the default destination profiles. The Mobile IP application can use the default destination profile. You can modify the configuration of the default destination profiles.
