The case for more versatile BGP Route Reflectors
Olivier Bonaventure, Steve Uhlig and Bruno Quoitin
The Border Gateway Protocol (BGP) is the standard interdomain
routing protocol in the Internet. Inside an Autonomous System (AS),
the interdomain routes are often distributed by using BGP Route
Reflectors (RR). Today, most RR are simple BGP routers. We show that
by adding intelligence to the RR, it is possible to improve both the
routing and the packet forwarding in ASes. We show how a versatile RR
can help an AS to engineer the flow of its incoming or outgoing
interdomain traffic. We also discuss how a versatile RR could help to
reduce the BGP convergence time or reduce the size of the routing
tables when providing BGP/MPLS VPN services.
