Benefits
• Provides industry's most robust, scalable, and
feature-rich internetworking software support using
the accepted standard networking software for Internet
and private WANs
• Constitutes part of the Cisco end-to-end network
solution
• Offers support for advanced QoS features such as the
Resource Reservation Protocol (RSVP), Weighted Fair
Queuing (WFQ), and IP Precedence to reduce recurring
WAN costs
• QoS features (such as committed access rate [CAR],
policy routing, low-latency queuing [LLQ], generic
traffic shaping [GTS], Frame Relay traffic shaping
[FRTS], and RSVP) allocate WAN bandwidth to priority
applications for improved performance
• Allows expandability to support services such as
hardware-assisted encryption
• Allows internal users to access the Internet with
secure, per-application-based, dynamic access control
while preventing unauthorized Internet users from
accessing the internal LAN
• Provides high-speed hardware-assisted encryption up
to T1/E1 performance
• Enables creation of wire-speed VPNs by providing
industry-standard data privacy, integrity, and
authenticity as data traverses public networks
• Ensures proper identity and authenticity of devices
and data
• Enables scalability to very large IPSec networks
through automated key management
• Allows any standards-based IPSec or L2TP client to
interoperate with Cisco IOS tunneling technologies
• Allows the router to act as remote VPN client and have
VPN polices pushed down from the VPN concentrator
• Allows the router to terminate remote access VPNs
initiated by mobile and remote workers running Cisco
VPN client software on PCs; and allows the router to
terminate site-site VPNs initiated by IOS routers using
the Cisco Easy VPN Remote feature
