Who is Vulnerable?
Vulnerability Description BGP (Border Gateway Protocol) is an application layer distance vector routing protocol. Attacks on the BGP protocol may target either a vulnerability in the routing software/hardware used or attack the routing information of the network (for example, by vicious advertising routers). Authenticating BGP communication between peers enhances the security of BGP.
