Re: Question: ip ospf network point-to-multipoint vs

what i understandfor point-to-multipoint you have to have Broadcast support
on underlaying frame relay mapings on hub and spoke. and also all spokes
should have a mapping to each other via same DLCI which is mapping to hub.
In point-to-point you dont need to map to each spoke or hub as you will use
interface dlci command. This simplifies the operation. Timers for both type
will be same.
