Experts, is the following true?

If ISIS is configured across an ae interface, due to the hashing algorithm, all hello frames will use the same member link; due to the convergence time for LACP being higher than ISIS holdtime of the adjacency, if that link fails, ISIS will flap before reconverging over the remaining member link(s).
For this reason it is probably not such a great idea this set-up.

Cheers,
