Mixture of Point-to-Point and Multipoint frame-relay

R1 est configuré en « point to point » vers R4, et en « multipoint » vers R2 et R3
Les interfaces « point-to-point » utilisent « frame-relay interface-dlci » pour indiquer le N° de DLCI
Les interfaces « multipoint » utilisent « frame-relay map ip » pour indiquer le N° de DLCI

remarques:

en mode multipoint, inverse-arp doir être désactivé
inverse-arp est désactivé automatiquement dans une sous-interface
