The ISP-BGP Discussion List is for ISP technicians, network administrators, engineers, Internet architects and other professionals that need to further or share their understanding of the Border Gateway Protocol.

Simply defined, BGP enables groups of routers or autonomous systems to share routing information in order to establish efficient, loop-free routes. BGP is commonly used within and between ISPs. The protocol is further defined in RFC1771.

Topics for discussion include scaling issues, class-B network address space, routing tables, multi-homing, software management, classless inter-domain routing (CIDR), and IP network number allocations. Discussion occasionally takes a theoretical turn as technicians discuss long-term remedies for network address space conservation.
