Hi, I'm working for a company and we want to employ an additional WAN link with a seperate provider, for redundancy purposes, along with a seperate router for each link.<br />
<br />
My question is: each router, I guess, I will have its own internal and external IP address. Is there a way that this can be configured so that each router will automatically pickup the load if one fails? Or can they be used for load balancing?<br />
<br />
I'm sure this can be done, but how? If each client is using the IP address for the default gateway of say, the first router, then if this router or the link it's connected to fails, then how will the clients redirect automatically to the second router?<br />
<br />
I would want to use Cisco kit ideally, is there some Cisco IOS features that can do this? Thanks.

Multiple WAN links and routers for redundancy

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.

Network Architecture

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
