Required Information
Description
HA service name
This is an identification string between 1 and 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.
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.
UDP port number for
Mobile IP traffic
Mobile IP traffic
Specifies the port used by the HA service and the FA for communications. The UDP port number can
be any integer value between 1 and 65535. The default value is 434.
be any integer value between 1 and 65535. The default value is 434.
Mobile node re-
registration requirements
registration requirements
Specifies how the system should handle authentication for mobile node re-registrations.
The HA service can be configured as follows:Always require authentication
Never require authentication (NOTE: the initial registration and de-registration will still be handled
normally)
Never look for mn-aaa extension
Not require authentication but will authenticate if mn-aaa extension present

Information
FA IP address:
The HA service allows the creation of a security profile that can be associated with a particular FA.
This specifies the IP address of the FA that the HA service will be communicating with.
Multiple FA addresses are needed if the HA will be communicating with multiple FAs.

This specifies the IP address of the FA that the HA service will be communicating with.
Multiple FA addresses are needed if the HA will be communicating with multiple FAs.
Index:
Specifies the shared SPI between the HA service and a particular FA. The SPI can be configured to
any integer value between 256 and 4294967295.
Multiple SPIs can be configured if the HA service is to communicate with multiple FAs.

any integer value between 256 and 4294967295.
Multiple SPIs can be configured if the HA service is to communicate with multiple FAs.
Secret:
Specifies the shared SPI secret between the HA service and the FA. The secret can be between 1 and
127 characters (alpha and/or numeric).
An SPI secret is required for each SPI configured.
Specifies the shared SPI secret between the HA service and the FA. The secret can be between 1 and
127 characters (alpha and/or numeric).
An SPI secret is required for each SPI configured.
Hash-algorithm:
Specifies the algorithm used to hash the SPI and SPI secret. The possible algorithms that can be
configured are MD5 per RFC 1321 and keyed-MD5 per RFC 2002. The default algorithm is hmac-
md5.
A hash-algorithm is required for each SPI configured.
