There isn't much you can do afaik: STP on ACs (CE-only, and consistent port
configurations / prone PVSTP), waiting for MST-AG or even MC LAG, keep away
from loop-capable ACs per L2 site.
I'am really missing here s/w support for H-VPLS based setups. Currently I see
no way other then running
Team,
MST AG is in roadmap to solve this problem.

Does that actually help? Does a 3560 merge multiple VLANs into a single
topology if they happen to use the same ports everywhere?
Different varieties of spanning tree do different things:
802.1d / 802.1w RSTP: single topology for all vlans

there's no 128 vlan limit - it's a spanning tree topology limit of 128

Hi Aaron,
Wouldn't the tunneling of STP and letting CE switches to block out the
redundant paths an option?

with rstp you can have a different topology per vlan, but you max out at
128 vlans. With MST you're stuck with 16 topologies per area, but you can
use all 4094 vlans.

I believe you mean PVRST and not RSTP.

yep, correct - that should have been clear from the context. I don't use
vanilla rstp anywhere because single topologies just don't work with
nontrivial L2 configurations.

This is an option. Thanks Adam, and it works with efp (si) command
