What is Multi-Homing?
Multi-homing is the process of selecting, provisioning, and installing a redundant connection to the Internet. Could be the same provider, or a different provider.
Why Multi-Home?
Slow is 1,000,000% better than dead. You may be out of bandwidth. And Telco circuits die. Routers die. Providers’ networks fail. Different networks have better performance to different sites.
A Multi-Homed Architecture
Ideally, take advantage of the opportunity to multi-home to remove all single points of failure in your network. Use - Multiple providers, unless your current provider will let you have cheap backup Multiple routers Multiple telco vendors
Multi-Homed Architecture
Two routers, each with a different WAN connection from a different telco vendor. Use HSRP or VRRP internally to make both routers look like one “virtual” router. Eventually, multiple providers. Upcoming Boardwatch article with configs.
How the Internet Works
Well, it breaks more than it works but when it does work - The Internet is a network of networks. Each network (called Autonomous System) on the Internet announces “routes”, which are lists of the IP addresses of the boxes on their network. You need to be able to send packets *to*, and get packets *from*, everywhere.
