Chapter 4 Configuring Multiprotocol Label Switching
Session Limit Per VRF
• VPDN parameters configured for the individual VPDN group are always applied to that VPDN
group.
• System default settings for VPDN parameters are applied for any settings not configured in the
individual VPDN group or VPDN template.
VPDN Template Configuration
Not all commands that are available for configuring a VPDN group can be used to configure a VPDN
template. For a list of the commands available for VPDN template configuration, see the vpdn-template
command reference page in the Session Limit Per VRF, Release 12.2(4)B feature module.
Feature History for Session Limit Per VRF
Restrictions for Session Limit Per VRF
The session limit Per VRF feature has the following restrictions:
• Nesting of VPDN templates is not supported. You can associate a VPDN group with only one VPDN
template at a time. If you associate a VPDN group with a named VPDN template and then with a
second VPDN template, the VPDN group is detached from the first VPDN template and associated
with the second template.
• If you attempt to associate a VPDN group with a named VPDN template that you have not
configured, the VPDN group uses the system defaults.
• The session-limit global configuration command takes precedence over the group session-limit
VPDN template configuration command.
• If the VPDN group value is less than the VPDN template value, the VPDN group session limit takes
precedence over the VPDN template session limit.
Prerequisites for Session Limit Per VRF
The session limit Per VRF feature has the following requirements:
• You must have a VPDN enabled on the router and at least one VPDN group configured. The router
must make an L2TP connection before VPDN configurations can be established.
