LAN-to-LAN Features
Integrated Bridging and Routing (IRB) Enables scalable, efficient integration of Layer 2 and Layer 3 domains; allows extension
of VLANs while maintaining ability to interconnect them to routed domains through the
same router
Encryption Supports IPSec with 56- or 168-bit Data Encryption Standard (DES) packet-level
encryption
Hardware Compression Provides for compression of up to two full-duplex E1 lines using STAC (QIC-122)
compression
Software Compression Supports STAC or Predictor algorithms for slow-speed serial links
AppleTalk Access List Control (AT ALC)
Enhancements
Supports AT fast-switched or inbound access lists
IP and IPX
™
Named Access Lists Allows easier identification of simple and extended access lists; allows ACL modification
without deleting and reconfiguring
Frame Relay Traffic Shaping Provides Committed Information Rate (CIR) enforcement on a per-virtual circuit basis;
can throttle traffic-based BECN marked packets from a Frame Relay network
Frame Relay Forum .9 (FRF.9) Software
Compression
Provides significantly higher compression ratios with a stream-oriented, multivendor
compatibility with the ability to maintain multiple compression and decompression
histories on a per-DLCI basis
Frame Relay Switched Virtual Circuits (SVCs) Provides cost savings over a Permanent Virtual Circuit (PVC) connection via usage-based
pricing; allows dynamic modification of network topologies
X.25 over ISDN D-channel Allows a dialer to initiate X.25-over-D-channel calls; supports static TEIs
X.25 Enhancements Supports X.25 over TCP (XOT)
Protocol Translation Virtual Templates Simplifies configuration process for protocol translation to tunnel point-to-point protocol
(PPP) across TCP, X.25, and LAT networks; supports dynamic creation of virtual access
interface that only lasts as long as a tunnel session is active
Hot Standby Router Protocol (HSRP) over
Inter-Switch Link (ISL)
Supports HSRP between standby and active HSRP groups in a VLAN environment
AppleTalk, DECNet, VINES, IPX Encapsulations
over ISL
Supports these protocols over ISL
Fast Switches Policy-Based Routing Improves switching performance; creates more opportunities to utilize policy routing
Multiservice Features
Resource Reservation Protocol (RSVP) Allows coexistence of multimedia applications with “bursty” applications on the same
infrastructure; enables guaranteed quality of service (QoS) for Voice over IP (VoIP) and
other multimedia applications
Random Early Detection (RED) Provides congestion avoidance mechanism for TCP applications
Routing Table Protocol (RTP) Header
Compression
Compresses IP/UDP/RTP header from 40 bytes to five bytes; beneficial when running
VoIP over slow links, especially when RTP payload is less than 50 bytes
Generic Traffic Shaping Limits packet loss by throttling transmission rates at the source to improve service
predictability
Voice over IP (VoIP) and Voice over Frame Relay
(VoFR)
Allows integrated voice/data for multiservice networks
FRF.11 and FRF.12 Standards based VoFr and Frame Relay QoS
