I've done close reading of both the User Guide and CLI manual but I'm not clear on the interaction (i.e, "gotchas"), if any, that spanning tree (STP, RSTP, RSTP-PV, etc.) has wiith respect to virtual routed interfaces. I know other equipment mfrs. (cough, cough ... B****ade) go to some length to describe the issue; i.e., that virtual interfaces are subject to the rules of STP if they are all in the same domain and are thus blocked for the routed protocols if not in the forwarding state. Would this kind of operation also be true of the N-series? What about the case of per-VLAN spanning tree? Since it's per-VLAN would this still apply? Wouldn't the spanning tree "terminate" at each virtual interface as opposed to grouping them all in one large domain as would be the case with (R)STP?
Virtual routed interfaces, as opposed to port-based routing, is, for me, a murky area with respect to STP and it's variations. Any in-depth knowledge that one could share would be appreciated.
