Re: [nsp] RSP4 and RSP8 together?

Hi Gert,

Basically all bets are off on which gets elected master and which
get's elected slave if you mix RSP8 with RSP2 or RSP4.

If a crash just occurred, that RSP which crashed will elect to be
the slave on the next boot. This is reliable. But on subsequent
boots or power cycles of the router, which RSP will elect to be
the master is not deterministic if mixed RSP8 and other RSPs
are used.

So for this reason we don't officially support mixed RSP8s
with other RSPs.

Thanks,
