POINT TO MULTIPOINT ADVANTAGE

FANDKMCC

HELLO

Does anyone know of an advantage or benefit which point to multipoint has over point to point?

cheers

ONe example is the fact that branch locations don;t have to through the HUB location to get to another branch location. They can go straight through the frame-relay network, across the PVC that you are paying for, to the other branch office.

The location of your enterprise servers and data flow are usaually the deciding factors in point-to-point and mulitpoint interfaces.

multipoint allows you to have a mesh or partial mesh network.

The only advantage to multipoint is it saves on address space and reduces the number of subnets in the routing table. Back in the days of fixed length subnet masks, each point to point interface would eat up lots of addresses because there are only 2 devices but you may be using a /27 mask or even worse a /24 where 252 addresses are being wasted. With VLSM this is not reall a concern anymore, but reducing the size of the routing table may be, so a mulipoint interface may be better than 20-30 point to point subinterfaces.

Thanks guys. Hadn't thought of either of those.

the main reason to have point to multi point is to save money on leased lines and interfaces.

The virtual circuits cost the same amount regardless of how your configure them.
