I've never seen a protocol that handled flapping well :/
I really wish somebody would design a routing protocol with extensions
fordetermining bandwidth tho (sound familiar? :/ )

The biggest issue we have with MSTP is the inability to deal with
unstable links. A high capacity backhaul flapping is disastrous with
MSTP due to the constant bridge table flushing. G.8032 should be able
to deal with this type of failure more gracefully. I think MPLS also
has ways of dealing with it but I have not investigated that route as
much of our existing equipment does not support MPLS. We have to
deploy new equipment at the tower sites so MPLS would be an option,
but so far we are thinking MEF over MPLS solutions.

This info may be a bit outdated with MSTP, I haven't looked, but it
used to be that the size of your tree should beno larger than 7 nodes.

Do you really need something faster than one of the spanning tree
variants?
The topology at Montana Internet is to have a layer 3 switch at each
site and a big flat rapid spanning tree ring for all of the OSPF
speaking layer 3 switches (Aka routers) to talk on. If I yank a
ring cable, I lose about a second on two is all.

Looking to add Ethernet ring protection switching into our
network. I've attached a PDF demonstrating the topology of the
test tower set. I'm leaning toward a G.8032v2 implementation
simply because it's ITU standards based and not vendor specific.
Other options include Brocade MRP, Moxa Turbo Chain, etc. Any
shared wisdom would be greatly appreciate before we get
ourselves pot committed.
