Say we have a diamond shaped network, with home, first, second and third bases.
The OSPF COST is the same for both home to third baseand home to first, and packets end up
going to second base and to the end customer
I understand traffic to the customer will be split by connection across the two outgoing routes, but
what about the return traffic?
The router at second will have a default route to either third base or first base but not both.
Will the
return packets take alternating routes back to home, or will they 'remember' which route they took
to get to the end customer, and follow the same path back, or will they take the default route at
second base and always come back the same way?
That last allows for load balancing on the outgo, but not on the return.
How to get balancing to happen in both directions?
