Why should they need to connect ot the same upstream switch? RTG or flexlink is only run local on the TOR or Access Switch, the upstream switch does not need to know about it. You can connect the access switch running RTG/flexlink to two different Core Switches without any problems. We do this in basically all of our datacenters. You only need to make sure, that the Core to Core Switch Link does not fail or at least is redundant enough, otherwise you may end up with a split situation as RTG/flexlink does not know about link errors upstream. regards Tobias _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
