[j-nsp] MX960 Redundant RE problem

[Morgan McLean]

Correct me if I'm wrong, but backup routing engines never have adjacencies
or peering relationships etc because they are not active, correct? When
they become master they have to reestablish those sessions. Thats how it
seems to be for our SRX routing engines, at least, but routes are shared
between the two so that during the time it takes for those things to
reestablish, the routes are still moving traffic.

I might be wrong, but that was my impression.
