[c-nsp] gigabit ethernet ring for metro ethernet deployment

[Fetzer, Bryan]

Rick, 

We provide transparent LAN services to our customers. We have a ring
topology around many cities and carry many customers VLAN's unfettered.
Your solution would be fine

in the case where I was simple attempting to provide my own ISP IP
transport services, but that isn't the case for many NSP's attempting to
offer a customer transparent LAN services when they have numerous sites
around a city or state. 

EAPS is hardly a fancy or difficult thing to setup. Nor is it expensive.
In fact, you can run EAPS on Extreme's lowest platforms, albeit only one
ring but for many one ring will probably suffice.
