Peter,
If I peered with your three locations, and set the cost of each link to be proportional to the distance (or at least speed/latency), then my network would prefer the link with the lowest cost, but still have the other links as redundant in the case of a link failure.
The routing problems are similar to those with BGP. If I'm routing to your AS number, I'm going to want to hand it over to the geographically closest point, and assume your network is better at connecting all of it's internal parts. BGP AS's don't expose the internal structure of the network either.

It;s no different than I-ISIS.
Within a area you treat all the boarder gateways (are routers) the
same, so for itgoing packets a node inside the area will pick it's
closest area router with external connectivity to senda outgoing
packet through.
Another area will pick ANY router it think is usefulle for the
destination area, regardless of the internal topology of that area..
Bottom line:
I have area 59 in Stockholm, Uppsala, Reston VA, and Sunnnyvave CA, if
we want to have a usefull "global core" it needs to be in the same
area....

Brian, would you like to get this all joined in to the mesh? Is a NA
hub still needed or has someone else offered one? (This'd be on an
unmetered gigE pipe)

I think running a hub on an emulated router maybe isn't the best idea.
(sorry to say so)

We also have to take in to account how to get some kind of resonalble
routing, as the inside of an area is not exchanged with other areas.

Hello!
It is a thought. A good one at that. One problem or crisis at a time though.

Indeed, they *are* BSD. Pre-SysV SunOS was based on BSD4.1C.

I'm keeping my VME Suns, but I can help you with the software.

Hello!
It is a thought. This does not explain why one of them has six legs
and is trying walk out your doors to hitchhike its way here.
