Re: Is it time to abandon bogon prefix filters?

Again, I think bogon filters are a bad idea for unmanaged or
semi-managed routers (or inclusion as a "default" in anything,
i.e. Cisco's auto-secure).

You make a very good point about the difference between routers that
are being routinely maintained by highly clueful people and routers
that are in the field and untouched/unloved for months to years at a
time.

in the field != untouched/unloved

i contend that all one's routers should be rigorously configured as
programmatically as possible.
