Re: 1 ASN versus 2 for BGP?
Just a remark: BGP by default DOES NOT support load-balance (it was not designet to do so). You can set default path for your AS but you can not influence to other AS.

A good current definition of AS, which isn't necessarily the one you see in Cisco training materials, is a set of addresses and routers, under one or more administrations, that presents a common routing policy to the Internet. In your example, company X is presenting the same routing policy to 4 ISP's. It should use a single ASN. -- "What Problem are you trying to solve?" ***send Cisco questions to the list, so all can benefit -- not directly to me*** Howard C.

1 ASN versus 2 for BGP?
Suppose I set up BGP multihoming from company X site A to 2 ISPs (load balance). If I decide to additionally set up BGP multihoming from company X site B to 2 other ISPs (load balance), can I still use company X's ASN or do I need to get a second ASN? My guess is that I need 1 ASN. Would there be a time when I'd need 2 ASNs? - Jennifer _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
