Hi Folks,

I want to load balance multiple GRE tunnels over a number of circuits
between a couple of routers. Since the routers will load balance
per-flow and not per-packet, will the routers be able to distinguish
between the tunnels ?

The problem is that the tunnels will all be between the same IP
addresses. AFAIK the layer3/4 info the router will use to load-balance
is as follows:

    * Source IP address
    * Destination IP address
    * Protocol
    * Source port number
    * Destination port number
    * Incoming interface index


Since all of these will be identical, what will happen?

Thanks,
Leigh Porter
