Speed up the email traffic and response as the traffic goes around the world. &nbsp;<br />
<br />
i cannot directly configure the routers in leased line to use EIGRP and static route as a VRF is running in the main site to prevent IP conflict (IP migration is on-going). <br />
<br />
i can't find a way for the email server only to pass the routers as the primary line and use the WAN as secondary line in case the primary fails. <br />

Hi, how do i tell the cisco 6509 to use the leased line as primary line and use secondary WAN via MPLS when an email traffic from exchange is seen? <br />
<br />
I got two 6509 on two sites and i placed a leased line in between, which is where the traffic should run for email only. first site is using static IP route the second site is using eigrp. the catch is there is an ip conflict if i open the whole network that is why i should only pass email traffic and block all the rest as it should use the existing WAN (a NAT is being used elsewhere to prevent the ip conflict). Also, would it be possible to tell the router or switch to use the WAN as secondary link in case the leased line fails? &nbsp;

use Cisco class map as main traffic route

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

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 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.
