Chapter 4 Observing System Startup and Performing a Basic Configuration

Configuring a Cisco 7200 VXR Router

Step 6 For the following queries, do not enable VINES, LAT, DECnet, CLNS, bridging, XNS, or Apollo:

Configure Vines? [no]:

Configure LAT? [no]:

Configure DECnet? [no]:

Configure CLNS? [no]:

Configure bridging? [no]:

Configure XNS? [no]:

Configure Apollo? [no]:

Step 7 For the following queries, enable routing on AppleTalk and IPX:

Configure AppleTalk? [no]: yes

Multizone networks? [no]: yes

Configure IPX? [no]: yes

Step 8 In most cases you use IP routing. If you are using IP routing, you must also select an interior routing protocol. You can specify only one of two interior routing protocols to operate on your system using the setup facility: Interior Gateway Routing Protocol (IGRP) or Routing Information Protocol (RIP).

To configure IP routing, enter yes (the default) or press Return, and then select an interior routing protocol:

Configure IP? [yes]:

Configure IGRP routing? [yes]:

Your IGRP autonomous system number [1]: 15

The following sample display includes a continuous listing of all configuration parameters selected in Step 3 through Step 8. Only IP, IPX, and AppleTalk are the selected protocols for this example.

Configuring global parameters:

Enter host name [Router]: router

The enable secret is a one-way cryptographic secret used instead of the enable password when it exists.

Enter enable secret: barney

The enable password is used when there is no enable secret and when using older software and some boot images.

Enter enable password: betty

Enter virtual terminal password: fred

Configure SNMP Network Management? [yes]:

Community string [public]:

Configure Vines? [no]:

Configure LAT? [no]:

Configure AppleTalk? [no]: yes

Multizone networks? [no]: yes

Configure DECnet? [no]:

Configure IP? [yes]:

Configure IGRP routing? [yes]:

Your IGRP autonomous system number [1]: 15

Configure RIP routing? [no]:

Configure CLNS? [no]: n

Configure bridging? [no]:

Configure IPX? [no]: yes

Configure XNS? [no]:

Configure Apollo? [no]:

7200 VXR specifications

The Cisco Systems 7200 VXR Series is a robust and highly scalable modular router designed to meet the demands of service providers and enterprises seeking high-performance solutions for their network infrastructures. Launched as part of the Cisco 7200 series, the VXR (Virtual Extensible Routing) variant enhances capabilities while providing effective support for a wide range of applications, including Internet Protocol (IP) routing, Voice over IP (VoIP), and Virtual Private Network (VPN) configurations.

At the core of the 7200 VXR is its modular design, which enables network administrators to customize the router according to their specific needs. The router supports a variety of interface cards, processing engines, and power supply options, ensuring flexibility for diverse network environments. This modularity facilitates easy upgrades and expansions, making it ideal for growing enterprises and service providers looking to future-proof their networks.

One of the standout features of the Cisco 7200 VXR is its impressive routing performance. It can handle a high level of traffic with low latency, which is critical for bandwidth-intensive applications. The router supports a wide array of routing protocols, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), and Integrated Intermediate System-to-Intermediate System (IS-IS), providing versatility for various network topologies.

The 7200 VXR also incorporates advanced features for enhanced security and reliability. With support for IPsec VPNs, it enables secure data transmission across untrusted networks. The router also includes features like Quality of Service (QoS) for prioritizing network traffic, ensuring critical applications receive the bandwidth they require even during peak loads.

In terms of scalability, the Cisco 7200 VXR can support hundreds of thousands of routes and MAC addresses, making it suitable for large metropolitan area networks (MANs) as well as enterprise backbone applications. It also provides the capability to support IPv4 and IPv6 networks, preparing organizations for a transition to next-generation internet protocols.

Additional characteristics of the Cisco 7200 VXR include enhanced manageability through the Cisco IOS software, which offers a comprehensive command-line interface and support for network management protocols. The router is also energy-efficient, with options for redundant power supplies that ensure continuous availability and minimal downtime in mission-critical applications.

Overall, the Cisco Systems 7200 VXR represents a powerful solution that combines performance, scalability, and security, making it an excellent choice for organizations looking to enhance their network capabilities in a rapidly evolving technological landscape.
