Abstract: Aiming at the suboptimal route selection problem in the Interior Gateway Protocol(IGP) cost induced by route reflection, this paper proposes an algorithm for optimal egress point check of iBGP route based on route reflection. This algorithm is operated in large-scale AS using C-BGP simulation. The results show that more than 20% potential suboptimal route can be obtained while there are parallel next-hops existing in the network.
