For which reason do you deploy BGP confederations within a BGP transit backbone?
A) to support a larger number of eBGP peer sessions
B) to increase the number of routes that can be redistributed between the running IGP and BGP
C) to reduce the number of eBGP routes that must be shared between autonomous systems
