My company has received a number of bids for a new WAN.
Info on the WAN
11 sites in a ring topology. Circumference of the ring is 200 miles.
Point to point Ethernet links between each site in the ring.
There will be "spurs" off of the ring in the future.
The bid that has been determined to be the "best" by management (i.e. cheapest) implements a Rapid Spanning Tree ring around the loop.
While a Layer 2 solution does allow for some flexibility...11 hops and 200 miles - this seems like a meltdown waiting to happen. Not to mention the spurs that will be added in the future, which could create a situation where traffic must span 13 switches from end to end, and the distance could be up to 230 miles.
Can RSTP be tuned to perform well in this environment? What kind of failover could be expected from such a design?
I admit my spanning tree knowledge is all LAN based, and in the LAN I have eliminiated STP as much as possible.
Feel free to mock and ridicule, my skin is thick.
