Bonjour, 

J'aimerais mettre en place une infra BGP avec le Route Reflector. J'ai configuré l'IBGP et l'EBGP et ça marche.

Pour l'instant je me concentre sur l'AS 65001. Mon problème et que les routeurs C1_A et C1_B n'arrive pas a apprendre les routes du RR.

Voici la configuration du routeur RR_C1.
