MLPPP splits, recombines, and sequence datagrams across multiple logical links. The use of MLPPP increases throughput between two sites by grouping interfaces and then load balancing packets over the grouped interfaces (called a bundle). Splitting packets at one end packet by packet, sending them over the bundled interfaces, and recombining them at the other end achieves load balancing.

No, it will send a packet out if each interface in a round robin fashion and sequence them to be reordered correctly on the other end.

Just ensure that the links that are bundled are of the same bandwidth.

When you bundle 2 links with different bandwdith, the loadbalance fails and ends up having problems

I had actually raised a case with even TAC on how loadbalancing occurs when you have different badnwidth links on the multilink but didn't get a satisfying response




Hi Mohammad

Info provided by Narayan says diff, it is like..........

Multilink does not round-robin packets. It give data to the links on demand.

Several small frames may land on one link to balance a large frame on another link. A fast link draws more data than a slow link. Over time, the amount of data sent on each link is proportional to its bandwidth.
