[j-nsp] Experience with Junos 15.1 on MX960?

[Karl Gerhard]

Hello

we've had very bad experience with Junos 15.1 on our switches (EX4550, EX4300, EX4200).
Now we're getting new MX960s with 2xRE-S-X6-64G and unfortunately the minimum required Junos version for this RE is 15.1. Can anyone share their experience with Junos 15.1 on MX960? Is it as bad as it is on the switches? Would it be wiser to jump directly to 16.1/16.2/17.1/17.2/17.3?

We're especially interested in bugs/problems related to MC-LAG.

Regards
Karl
