Question about sections 3.1.2-3.1.4.

During the discussions on global-v6, a scenario came up that caused trouble.

Imagine network A does not (under current RIR rules) qualify for a /35.
Network A has routes to network B via (a) a high speed direct connection,
(b) a high-speed network and (c) an ordinary commodity internet connection.
Network A provides connectivity to a number of sites (< 200) not under its
direct control.

In IPv4, where Network A has an ASN and allocation from a RIR, BGP localprefs
enforce a routing policy which uses the high-speed connects in preference to
the commodity internet.

Does section 3.1.4 require a solution to this scenario? "class of traffic"
might just mean a protocol or could be wider, so I am not sure.

The reason I bring this up is that it is not an unusual configuration for a
national research network. If the answer is "no" then it is not necessarily
a problem with the document :) but if the group [does|does not] plan to
address it, I think it would be useful feedback for the policy groups.

Best regards,
Dave
