i have 2 sites connected via 4 wan links in a point to point. i want to equally distribute the traffic on the 4 links - using ip cef per-packet load sharing.
the problem will be that i will get packets out of order.
i though of using a gre tunnel as a solution for that,
a single gre tunnel which will see the remote gre tunnel through the 4 wan links and send each packet to different wan link. at the remote site single gre will collect the traffic from the 4 links and use the sequence number on its header to make the "in order delivery" toward the application.
is this can work ?
if it can, how much traffic this kind of solution can forward ?
