Hello Leigh,

Per flow load balancing is based on 5 tuppels, but with GRE with between the two same IPs the two tunnels appear like a single flow. I would suggest sourcing the tunnels from the DASL addresses (assuming they are not dynamic) so the two tunnels will be treated as two flows.

I would also like to do this but does anybody know if the per-flow load
balancing will correctly distribute multiple GRE sessions between the
same pair of IP addresses fairly across the two paths?

AFAIK it will NOT do this and so per-flow load balancing will not always
... balance :)

Thanks,

I guess you have two static routes. If this is the case, as you know first
of all the 2 routes should have the same prefix length (10.0.0.0/24,
0.0.0.0/0 etc) and Preference. You need to make these preferences equal
either by configuring policy to set the preference/metric value same.

To enable per-flow load balancing, you must set the load-balance per-packet
action in routing policy configuration.

policy-statement please-load-balance {
    then {
        load-balance per-packet;
    }
}
