Restrictions For Ppp Sessions And L2Tp Tunnel Scaling - Cisco ASR1002 - ASR 1002 Router Software Configuration Manual

PPP Sessions and L2TP Tunnel Scaling
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.
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

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.
