Layer 4 Redirect Scaling
The ASR 1000 supports the ability to redirect IP traffic within an ISG traffic class. Layer 4 redirect
scaling is performed by the Quantum Flow Processor (QFP). The scaling limits are dependent on the
ESP. Table 21 lists the ESP and the default per-session limit.
Configuring the Cisco ASR 1000 Series Router for High
Scalability
The Cisco ASR 1000 Series Routers provide powerful performance and scalability for embedded
services.
To achieve maximum scaling on the 1001, 1002, and 1004 chassis, IOS software redundancy must be
d
isabled. For more information about restrictions and limitations, see the “Restrictions for PPP Sessions
and L2TP Tunnel Scaling” section on page 2.
To ensure high scalability on the Cisco ASR 1000 Series Router, perform the following configuration
