How design a Routing with 2 WAN's

[danielscharf]

Hello,

we want to extend our company-network with a second wan (another provider) mainly used for critical business-applications and voice.

Where can I look for some Informations about designing a routing for that wan-structure?

Thanks for help

Hi Daniel,

If you have 2 ISP terminating on single router simple config will be PBR which is policy base routing.

Once the traffic hits the lan interface it will be classified based on ACLs and once classified exit interface can be set or specified.

Have a look at thislink as how to cofnigure PBR

I am not exactly shure what you want.

If you want some kind of redundancy or load balancing, you're looking at multihoming and/policy based routing.

Multihoming can be achieved with or without BGP. If you have redundant connections to the Internet, you can influence outbound traffic by configuring a routing policy to either load balance traffic according to your routing policy.

E.g. critical business-applications and voice are sent to ISP 1 and web-browsing and ftp are sent to ISP 2.

I included several links that can help you in finding the right solution.
