Sometimes you notice a network design where you have more
than one serial link between two routers. A single serial link doesn’t
provide enough bandwidth or maybe in case you want some extra redundancy. All the
interfaces on a router need a different IP address, a design that looks like
this:
Multilink PPP allows us to make a combination of multiple
physical serial links into a single logical link or MLP bundle. MLP is used to aggregate multiple WAN links into one logical
channel for the transportation of traffic from one router to another, MLP enable the load—balancing of traffic from different links as we and allows some level of redundancy in case of line failure on a single link.MLP Supports a maximum of ten member links per bundle or single logical link.
lets take a look of its configuration:
