Mobile IP Configuration Examples
Table 6. Required Information for Destination Context Configuration
Required Description
Information
Destination This is an identification string between 1 and 79 characters (alpha and/or numeric) by which the destination
context name context will be recognized by the system.
NOTE: For this configuration, the destination context name should not match the domain name of a specific
domain.
PDN Interface Configuration
PDN interface This is an identification string between 1 and 79 characters (alpha and/or numeric) by which the interface will
name be recognized by the system.
Multiple names are needed if multiple interfaces will be configured.PDN interfaces are configured in the
destination context.
IP address and These will be assigned to the PDN interface.
subnet Multiple addresses and/or subnets are needed if multiple interfaces will be configured.
Physical port This specifies the physical port to which the interface will be bound. Ports are identified by the chassis slot
number number where the line card resides in, followed by the number of the physical connector on the line card. For
example, port 17/1 identifies connector number 1 on the card in slot 17.
A single physical port can facilitate multiple interfaces.
Physical port This is an identification string between 1 and 79 characters (alpha and/or numeric) by which the physical port
description will be recognized by the system.Multiple descriptions are needed if multiple ports will be used.
Physical ports are configured within the destination context and are used to bind logical PDN interfaces.
Gateway IP Used when configuring static routes from the PDN interface(s) to a specific network.
