problems with the aci range too small?

[Paul Syverson]

Mat is correct about what the OR papers say. And, I think that is
essentially the same as what Roger is suggesting.

The only issue I can think of as a potential problem is router twins.
If the aci space is allocated for each virtual router, then we would
need another bit or two to indicate which actual router is assigning
the name. But, I don't think that is (or should be for this and other
reasons) how router twins are handled.

Roger can better answer how twins are done now.

aloha,
