ISIS works on frame relay physical, multipoint subinterfaces, and point-to-point subinterfaces. The key issue is that ISIS only supports two network types, broadcast and point-to-point. There is no way to change network types as there is in OSPF.
Frame relay physical and multipoint subinterfaces will form neighbor relationships to other physical or MP subinterfaces (both are broadcast networks) but will not form neighbor relationships with point-to-point subinterfaces. FR point-to-point subinterfaces will only form neighbor relationships with other P-T-P subinterfaces. Cheers, Fred. > You need to use p2p sub in terfaces.
