[j-nsp] The status of VLAN ID spaces on the MX

Hi everyone,

Suppose that I have redundant aggregation switches, S1 and S2.  Every
access device gets an uplink from each.  S1 and S2 have a trunk
between them.  STP is running to break the loops.  All of this is at
layer 2.

Is there any way to provide multihomed VPLS to some or all VLANs
without introducing a forwarding loop?  I've been unable to come up
with an effective solution.

This is on MX if it makes a difference.

Ross
