The source context will facilitate the HA service(s), the Pi 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.
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.

Required Information for Source Context Configuration
Required Information
Description
Source context name
This is an identification string between 1 and 79 characters (alpha and/or numeric) by which the
source context will be recognized by the system.
NOTE: The name of the source context should be the same as the name of the context in which the
FA-context is configured if a separate system is being used to provide PDSN/FA functionality.
source context will be recognized by the system.
NOTE: The name of the source context should be the same as the name of the context in which the
FA-context is configured if a separate system is being used to provide PDSN/FA functionality.
Pi Interface Configuration
Pi interface name
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.
Pi interfaces are configured in the source context.
If this interface is being used for Interchassis Session Recovery, you must specify a loopback
interface type after the interface_name.

If this interface is being used for Interchassis Session Recovery, you must specify a loopback
interface type after the interface_name.
IP address and subnet
These will be assigned to the Pi interface.
Multiple addresses and/or subnets are needed if multiple interfaces will be configured.
Multiple addresses and/or subnets are needed if multiple interfaces will be configured.
Physical port number
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.

Physical port description
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 are needed if using multiple ports.
Physical ports are configured within the source context and are used to bind logical Pi interfaces.

Gateway IP address
Used when configuring static routes from the R-P interface(s) to a specific network.
