Cisco 7200 Series Routers Overview

The Cisco 7200 VXR Series Router delivers exceptional performance/price, modularity, and scalability in a compact form factor with a wide range of deployment options.

Cisco 7200 VXR Series Router

With processing speeds up to 2 million packets per second, port- and service adapters ranging from NxDS0 to Gigabit Ethernet, and OC-3 as well as an unparalleled number of high-touch IP services, the Cisco 7200 VXR series is the ideal Services Aggregation WAN/MAN edge device for enterprises and service providers deploying any of the following solutions:

• WAN edge-Award-winning quality-of-service (QoS) feature performance
• Broadband aggregation-Up to 16,000 Point-to-Point Protocol (PPP) sessions per chassis

The Cisco 7200 VXR Series offers a rich set of capabilities that address requirements for performance, density, high reliability, availability, serviceability, and manageability (Table 1).

Table 1. Cisco 7200 VXR Features and Benefit

Applications

VPN Gateways-With the new VPN Service Acceleration Module (VSA), the Cisco 7200 VXR provides high-performance, hardware-assisted encryption, key generation, and compression services suitable for site-to-site VPN applications.

• Broadband subscriber aggregation services-For small- and medium-density aggregation for network operators, competitive local exchange carriers (CLECs), Internet service providers (ISPs), post, telephone, and telegraph networks (PTTs), and enterprises worldwide. Key features include:
  • Flexible, modular interfaces for traffic aggregation: OC-3, Gigabit Ethernet, DS3, Fast Ethernet, Ethernet, POS
  • IP and ATM QoS/class of service (CoS)
  • MPLS VPN and full L2TP support
  • Feature-rich IP services and PPP termination support
• Multiservice capabilities-The Cisco 7200 VXR Series provides a scalable voice gateway solution, ranging from 2 to 20 T1s and E1s. The advanced QoS and multiservice features of the Cisco 7200 VXR Series makes it an ideal platform in a large number of enterprise and service provider deployments as managed multiservice CPE or as a voice gateway.
• Managed network services CPE-The Cisco 7200 VXR is a cost-effective CPE solution with a field upgradable modular platform. Key features for revenue-generating services include QoS, MPLS (MPLS VPN, MPLS QoS, MPLS TE), WAN edge services (VLAN support, NetFlow, NBAR), Security services (NAT, ACL, hardware encryption for VPNs), and voice/video/data integration.
• Enterprise WAN aggregation-The Cisco 7200 VXR provides a flexible aggregation solution that accommodates a wide range of connectivity and service options, offers high quality and reliability, and can scale to meet future requirements. The Cisco 7200 VXR's performance per price ratio in the DS0 to OC-3/STM1 range makes it the ideal platform for aggregating multiple branch offices or remote locations.
• IP-to-IP Gateway Support-Direct IP-interconnections between VoIP networks lower costs, lower latency, improve voice quality, and offer greater flexibility to support emerging services when compared with public-switched telephone network (PSTN) or time-division multiplexing (TDM) interconnections.

The Cisco Multiservice IP-to-IP Gateway provides a network-to-network interface point for:

• Signaling interworking (H.323, SIP)
• Media interworking (DTMF, fax, and modem)
• Address and port translations (privacy and topology hiding)
• Billing and CDR normalization
• QoS and bandwidth management (QoS marking using TOS)

Components

Table 3. Chassis

Table 4. Environmental Conditions

The Cisco 7200 VXR Series chassis also include a Multiservice Interchange (MIX), which supports switching of DS0 time slots via MIX interconnects across the midplane to each port adapter slot.

The midplane and the MIX also support distribution of clocking between channelized interfaces on the Cisco 7200 VXR to support voice and other constant-bit-rate applications. The VXR midplane provides two full-duplex 8.192-Mbps TDM streams between each port adapter slot and the MIX, which is capable of switching DS0s on all 12 8.192-Mbps streams. Each stream can support up to 128 DS0 channels.

The MIX in the Cisco 7200 VXR provides the ability to switch DS0 time slots between multichannel T1 and E1 interfaces, much like TDM capabilities. This enables the Cisco 7200 VXR to switch DS0 voice channels on a T1/E1 interface on one port adapter to and from separate voice-processing port adapters. It also enables DS0s to be switched through the Cisco 7200 VXR without any processing, which is a requirement in certain voice configurations.

Processors

The Cisco 7200 VXR Series sets new standards in meeting requirements for high-performance Layer 3 services at an affordable price for both service providers and enterprises.

The following processors are currently available for the Cisco 7200 VXR Series:

• NPE-G2
• NPE-G1
• NPE-400
• NPE-225

The NPE processors offer exceptional price/performance for most applications, including enterprise WAN aggregation, CPE, multiservice, and VPN. These processors provide the greatest flexibility when deploying new features.

Key features supported by the Cisco 7200 VXR Series processors include security, QoS, traffic management, and network management.

Protocols

The Cisco 7200 VXR Series Router supports the following standard Internet protocols:

• Layer 2 and Layer 3 protocols-Address Resolution Protocol (ARP), IPCP, IP forwarding, IP host, IP Multicast, PPP-over-ATM, TCP, Telnet, Trivial File Transfer Protocol (TFTP), User Datagram Protocol (UDP), transparent bridging, virtual LAN (VLAN), MPLS, and IPv6
• Layer 3 routing protocols-EIGRP, IGRP, IS-IS, OSPF, BGP, PIM, and RIP
• Network management and security-AAA, CHAP, FTP, RADIUS, SNMP, PAP, and TACACS
• RFC 1483-Multiprotocol Encapsulation over ATM AAL 5
• RFC 1577-Classical IP and ARP over ATM AAL 5
• ARP-Determines the destination MAC address of a host using its known IP address
• BOOTP-Uses connectionless transport layer (UDP); allows the switch (BOOTP client) to get its IP address from a BOOTP server
• Internet Control Message Protocol (ICMP)-Allows hosts to send error or control messages to other hosts; is a required part of IP; for example, the ping command uses ICMP echo requests to test if a destination is alive and reachable
• IP or IP over ATM-Suite used to send IP datagram packets between nodes on the Internet
• TCP-A reliable, full-duplex, connection-oriented end-to-end transport protocol running on top of IP; for example, the Telnet protocol uses the TCP/IP protocol suite
• Packet Internet groper (ping)-Tests the accessibility of a remote site by sending it an ICMP echo request and waiting for a reply
• TFTP-Downloads network software updates and configuration files (Flashcode) to workgroup switch products
• Reverse Address Resolution Protocol (RARP)-Determines an IP address knowing only a MAC address; for example, BOOTP and RARP broadcast requests are used to get IP addresses from a BOOTP or RARPD server
• Serial Line Internet Protocol (SLIP)-A version of IP that runs over serial links, allowing IP communications over the administrative interface
• PPP-Provides host-to-network and switch-to-switch connections over synchronous and asynchronous circuits
• Simple Network Management Protocol (SNMP)-Agents that process requests for network management stations and report exception conditions when they occur; requires access to information stored in a MIB
• Telnet-A terminal emulation protocol that allows remote access to the administrative interface of a switch over the network (in-band)
• UDP-Enables an application (such as an SNMP agent) on one system to send a datagram to an application (a network management station using SNMP) on another system; uses IP to deliver datagrams; TFTP uses UDP/IP protocol suites
• Dynamic Host Connection Protocol (DHCP)-Lets a host automatically obtain their IP address, subnet mask, and default route from a pre-configured DHCP server on the network
• Hot Standby Router Protocol (HSRP)-Provides fast cut-over to a backup router in the event of a system or link failure
