Cisco Cisco IOS Software Release 12.2(2)DD

This document describes the VPDN Group Session Limiting feature in Cisco IOS Release 12.2(2)DD. 
It includes the following sections:

Before the introduction of the Virtual Private Dial Network (VPDN) Group Session Limiting feature, 
you could only globally limit the number of VPDN sessions on a router with limits applied equally to 
all VPDN groups. Using the VPDN Group Session Limiting feature, you can limit the number of VPDN 
sessions allowed per VPDN group. This feature is implemented with the introduction of the 
session-limit number command in VPDN configuration mode. VPDN group session limiting is applied 
after the global VPDN session limiting (which is configured via the vpdn session-limit session 
command in configuration mode) is enforced. 

The VPDN Group Session Limiting feature gives more control to network administrators by enabling 
them to limit how many sessions a VPDN group can terminate. This feature enables service providers to 
cater to all types of organizations, large or small, by enabling finer configuration granularity.
