Modifying the Configuration of the Default Destination Profile
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.
To modify the configuration in the default destination profile:
- Specify the default destination profile for GRE or DVMRP.host1(config)#gre destination profile global any-virtual-router
- Modify the options for the default destination profile.host1(config-dest-profile)#tunnel mtu 5000 host1(config-dest-profile)#tunnel checksum
Note: You cannot configure a tunnel source, tunnel destination, or virtual router in the default destination profile.
