Desi nu am folosit IGRP si nu stiu daca e vreo diferentza la acest capitol
( nu am chef sa caut acum ), EIGRP face o metrica compozita dupa o formula
bazata pe 5 constante ( k1,k2,k3,k4,k5 ) si variabilile mentionate mai sus
BW, delay de interfata, reliability, load...etc ( cauta pe cisco: eigrp
composite metric sa gasesti formula.. e interesanta )
