Chapter 7 Broadband Scalability and Performance
PPP Sessions and L2TP Tunnel Scaling
lists the virtual circuit limits for ASR 1000 ATM SPAs, effective from Cisco IOS XE
Release 3.5.
Restrictions for PPP Sessions and L2TP Tunnel Scaling
This section lists the restrictions for the PPP sessions and L2TP tunnel scalability.
•
To achieve maximum scaling for the 1001, 1002, and 1004 chassis, we recommend software
redundancy be disabled for broadband applications, and only hardware redundancy be configured.
redundancy be disabled for broadband applications, and only hardware redundancy be configured.

Restrictions on 48000 session scaling with RP2 and ESP-40G include:
–
Intelligent Services Gateway (ISG) Services are not supported
