Controlling the redistribution of BGP routes

Sun, 04/01/2007 - 01:54 by Damien Leroy


This document proposes the redistribution extended community. This
new extended community allows a router to influence how a specific
route should be redistributed towards a specified set of eBGP
speakers. Several types of redistribution communities are proposed.
The first type may be used to indicate that a specific route should
not be announced over a specified set of eBGP sessions. The second
type may be used to indicate that the attached route should only be
announced with the NO_EXPORT community over the specified set of eBGP
sessions and the third type may be used to indicate that the attached
route should be prepended n times when announced over a specified set
of eBGP sessions.
