Hi,<br />
<br />
As you can see in the diagram attached below, I have four links between two of my sites. Two links are 10 Mbps capacity each and I am equally load balancing my traffic between them. Two more links are there of 200 Mbps capacity each and I am using them in active/standby state i.e. if one of the link goes down then the traffic is shifted to the other 200 Mbps link. All the links are L3 links.<br />
<br />
Currently I am using EIGRP only to route the traffic between both the sites on both the 10 Mbps links. I have configured specific static routes to use the 200 Mbps link only when the traffic is between 1.1.1.0/24 and 2.2.2.0/24 Servers.<br />
<br />
Now I want to configure routing using all the links in EIGRP in such a way that the two 10 Mbps links work in equal load balancing, the 200 Mbps links should work in active/standby mode i.e. traffic should shift to secondary 200 Mbps link only in case the primary link goes down.<br />
<br />
Any traffic with the destination of 2.2.2.0/24 servers should use the active 200 Mbps link and when the traffic is being generated/replied from 2.2.2.0/24 network should use the 200 Mbps active link. The traffic sourced/destined &nbsp;for Y.Y.Y.Y/Y network should use the 10 Mbps links only.<br />
<br />

Thanks in advance

Configuring Policy Basd Routing

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

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.

Routers

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
