Information Required; Source Context Configuration - Cisco ASR 5000 Series Administration Manual

Mobile IP Configuration Examples
The source context will facilitate the HA service(s), the Gi interfaces from the FA, and the AAA interfaces. The source
context will also be configured to provide Home AAA functionality for subscriber sessions. The destination context will
facilitate the PDN interface(s).

Information Required

Prior to configuring the system as shown in this example, there is a minimum amount of information required. The
following sections describe the information required to configure the source and destination contexts.

Source Context Configuration

The following table lists the information that is required to configure the source context.

Description
An identification string from 1 to 79 characters (alpha and/or numeric) by which the source context
will be recognized by the system.
This is an identification string between 1 and 79 characters (alpha and/or numeric) by which the
interface will be recognized by the system.
Multiple names are needed if multiple interfaces will be configured.
Gi interfaces are configured in the destination context.
These will be assigned to the Gi interface.
Multiple addresses and/or subnets are needed if multiple interfaces will be configured.
This specifies the physical port to which the interface will be bound. Ports are identified by the
chassis slot 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.
This is an identification string between 1 and 79 characters (alpha and/or numeric) by which the
physical port will be recognized by the system.
Multiple descriptions will be needed if multiple ports will be used.
Physical ports are configured within the destination context and are used to bind logical Gi interfaces.
Used when configuring static routes from the Gi interface(s) to a specific network.
An identification string from 1 to 63 characters (alpha and/or numeric) by which the HA service will
be recognized by the system.
Multiple names are needed if multiple HA services will be used.
HA services are configured in the destination context.
The port used by the HA service and the FA for communications. The UDP port number and can be
any integer value from 1 to 65535. The default value is 434.
