As an example we assign /48's to school districts,
If it is a really small school district, that is unlikely to expand beyond
16 sites, you could give them a /44, otherwise each district should get at
least a /40 or more. A university might need more, or maybe a /40 for
each college within it if each college within the university takes care of
their own needs. This gives them room to give each of their schools or
other sites a /48. Either way, the policy proposal would require SWIP for
the main block assigned to that district, but no SWIP requirement for
individual schools or other sites, all of which will be SWIP'ed to that
specific district or college.
The only reason you are complaining about the school districts getting
away without SWIP under the proposal is that you are assigning them too
small of a block. Each school, bus depot, admin headquarters, etc should
be getting a /48. I assume that instead you expect the districts to
assign smaller blocks to their sites, like a /56, instead of the
recommended /48.
Doing so follows the intent of the policy proposal to require larger
allocations (/47 or larger) to be SWIP'ed, but /48's belonging to a single
site without special routing not requiring SWIP. Doing this does
everything you want, because each assigned district block will be SWIP'ed
as a whole, making that district responsible. In the case of a
University, 2 levels of SWIP might be needed, one for the University, and
one under it for each College of that University, or other unit like a
facilities group.
I want each of them to have their own SWIP
records so any issues with traffic originating from the site can get
addressed
by the local network administrators before they get escalated up to me as
the WA-K20 NOC manager.
Give them the proper sized blocks, and your wish will be required by the
policy proposal. A /47 or more in the policy means ALL your assignments
to districts and colleges require SWIP, getting you out of the abuse loop.
It also relieves you and the district/college from any burden of having to
SWIP the individual sites of each district/college. Much better than the
current policy where you would be responsible to SWIP all the way down to
the site level, as the current standard is a /64 or more of static space.
