Effect of Route Reflection on IBGP Convergence and an approach to reduce convergence time
Request for Comments (RFCs) for Border gateway Protocol (BGP) suggest that the network topology using BGP must have full mesh of IBGP sessions to avoid routing loops. Routing loop is a condition where packets are routed between two or more routers resulting in slow convergence and routing instability. Route reflection is one of the strategies to avoid full mesh of internal BGP sessions between ...
متن کاملModeling BGP Route Selection within an AS
This paper presents a provably correct model that computes the outcome of the BGP decision process for each router in a single AS, without simulating the complex details of BGP message passing. The model requires only static inputs that can be easily obtained from the routers: the set of candidate routes to a destination (and the routers in the AS at which they were learned), import policies an...
متن کاملA novel internal BGP route distribution architecture
Route-Reflection and confederations were introduced to alleviate the scalability issue of maintaining a full-mesh of iBGP sessions. However, these techniques may lead to routing, forwarding, route diversity and sub-optimal routing issues. In this paper, we propose a new scalable internal BGP route distribution architecture that is rid of these issues. We propose an iBGP route distribution archi...
متن کاملQuantifying the BGP Routes Diversity Inside a Tier-1 Network
Many large ISP networks today rely on route-reflection [1] to allow their iBGP to scale. Route-reflection was officially introduced to limit the number of iBGP sessions, compared to the n×(n−1) 2 sessions required by an iBGP fullmesh. Besides its impact on the number of iBGP sessions, route-reflection has consequences on the diversity of the routes known to the routers inside an AS. In this pap...
متن کاملOptimizing IBGP route reflection network
In the conventional Internal Border Gateway Protocol (IBGP), the BGP sessions between all BGP speakers in a single Autonomous System (AS) form a full mesh. For scalability reasons, route reflection is proposed as an alternative to the full mesh inside an AS. The selection of route reflectors and their clients determines the paths used by IBGP route advertising. Thus, the design of the route ref...
