I am interested in implementing BGP but our company wants to know the disadvantages and the advantages of Border Gateway Protocol before we go that route.

Thanks. We'll let you know when a new response is added.

BGP is more of an external routing protocol for WAN networks. EIGRP is a great algorithm internally, but I’m not sure what your network is like, so I won’t bother you with baseless suggestions.

SearchTelecom and Cisco have very detailed information on BGP.

BGP is not used on a internal corporate network. IGP protocols, (OSPF or ISIS) are usually more suited for that. BGP is more often used when you are interconnecting backbones or using more advanced protocols like MPLS. In that case I assume you have yourself an AS of your own.

    I think the first step is to do a needs assessment, in some cases BGP is the way to go sometimes not. You have to be aware that BGP requires work, maintenance and testing. Plus all your gear must support BGP. Sometimes a NAT-based approach is better. What kind of environment are you using (#of isps / speed of each link / purpose of the project)? You can drop me a line at jph@elfiq.com if you want to explore. JP
