Re: [RRG] Re: [RAM] Different approaches for different protocols



The problem for sites arises if different ISPs give them different
prefix lengths --- that will really mess things up at the subnet
level.


No, you just zero out the prefix to the length that applies for that connection. As long as your subnetting fits within the longer prefix, you're still fine. If not, then you need a shorter prefix...

You do realize this requires a lot of site changes. Readdressing routers and doing longest match after the 6 bytes. Then the question is what if you want to use variable length subnet masks across your domain, etc.

There are a lot of administrative changes to make this work. If people are doubting the usefulness of Loc/ID split, adding more cost for the benefit will cause more resistance.
