Hi Paulo,

If you are just trying to make a fault tolerant link bundle between the
2 routers over a pair of links (of any type) there are a number of other
methods that you could use.

You may want to look at other methods of doing this. OSPF running on
the 2 routers could provide L3 fault tolerance over any link combination
if this is your goal.

Tom

I have a similar configuration with two wireless links using RouterOS
(Mikrotik) running at routers and netstream-dual option, in this case
link 1 only transport data from router A to B and link 2 transports
data from router B to A (L2), creating a real full-duplex wireless
connection between router A and B.

I am thinking to make something better then netstream-dual, using lagg
interface with lacp protocol to get more throughput when transporting
data from router A to B.

I will try to do something like full-duplex by now with two wireless
links using statics routes (L3), so all data from A to B pass through
link 1 and all data from B to A pass through link 2.

I would like to do balanced traffic across the two wireless links with
the greatest total speed from A to B. Reading man lagg I can do this,
but I didn't have success.

Paulo.
