Cisco Cisco IOS Software Release 12.4(2)XB6 テクニカルリファレンス

To enable the PDSN IPv6 functionality, use the cdma pdsn ipv6 command in global configuration mode. 
Use the now form of the command to disable this function.

cdma pdsn ipv6 {ra-count 1-5 [ra-interval 1-1800]}

no cdma pdsn ipv6 {ra-count 1-5 [ra-interval 1-1800]}

Global configuration

If the cdma pdsn ipv6 command is not entered, and a PDSN session is brought up with IPv6, the session 
will be terminated and the following message displayed:

%CDMA_PDSN-3-PDSNIPV6NOTENABLED: PDSN IPv6 feature has not been enabled.

The following example illustrates how to control the number and interval Routing Advertisements sent 
to the MN when an IPv6CP session comes up:

router(config)# cdma pdsn ipv6 ra-count 2 ra-interval 3

Route Advertisement count determines how many Routing Advertisements 
(RAs) to send out to the MN.

Number of IIPV6 route advertisements sent: the default value is 1. 

Route Advertisement interval determines how often Routing 
Advertisements (RAs) are sent to the MN.

The interval between IPv6 RAs sent (the unit of measure is in seconds, and 
the default value is 5). 

12.3(14)XY

This command was introduced.
