What is the advantage of using a multi-point interface instead of point-to-point sub-interfaces when configuring a Frame Relay hub in a hub-and-spoke topology?
It avoids split-horizon issues with distance vector routing protocols.|
IP addresses can be conserved if VLSM is not being used for subnetting.|
A multi-point interface offers greater security compared to point-to-point sub-interface configurations.|
The multiple IP network addresses required for a multi-point interface provide greater addressing flexibility over point-to-point configurations.|
Variable-Length Subnet Masking (VLSM) amounts to "subnetting subnets," which means that VLSM allows network engineers to divide an IP address space into a hierarchy of subnets of different sizes, making it possible to create subnets with very different host counts without wasting large numbers of addresses.
