PPP Sessions and L2TP Tunnel Scaling
The ASR 1000 Series Routers are deployed in a variety of broadband deployment models for terminating
Point-to-Point Protocol (PPP) Sessions and initiating or terminating Layer 2 Tunneling Protocol (L2TP)
tunnels. The maximum number of PPP sessions and L2TP tunnels is dependent on the hardware
combination. Table 18 lists the hardware combinat
ions and the maximum number of PPP sessions and
L2TP tunnels that are supported
in Cisco IOS XE Release 3.3. For information about the restrictions for
PPP sessions and L2TP tunnel scaling, see the “Restrictions for PPP Sessions and L2TP Tunnel Scaling”
section on page 2.
Table 19 l
ists 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.
• Restrictions on 48000 session scaling with RP2 and ESP-40G include:
