This initiative aims to simplify the process of ASN union. In today’s world there is a number of situations when several ASNs want to operate as one. The main goal of such ASN union is to get benefit from shared connectivity which includes customers, peers and upstream connections. BGP does not provide native support for such ASN unions, so engineers have to develop and support a number of ad-hoc solutions to make such networks operate properly:
- transmission of local preference values through ASN borders;
- ad-hoc to support “hot-potato” routing;
- synchronize communities to avoid route leaks.
We believe that such complexity could be resolved by using BGP Roles and extended BGP Confederations.
