3.2 Layer 3 : 3.2.a Compare routing concepts of EIGRP and OSPF (advanced distance vector vs. linked state, load balancing, path selection, path operations, metrics)
Lab Routage EIGRP
Introduction
EIGRP le protocole de routage à vecteur avancé propriétaire Cisco. Il est aisé à configurer, il est robuste et performant.
On trouvera ici un lab de configuration de EIGRP en IPv4 et en IPv6 dans une topologie maillée à trois routeurs.
