Wouldn?t this be the case of exchange based multi-homing solution? (as
described in RFC 2374)
Yes, I think we could obtain a PA allocation as an LIR from ARIN. I have
to admit I have philosophical objections to using our own address block--it
does nothing to minimize the size of the DFZ routing table. Is it better
to adopt the expedient solution now (using our own address block) rather
than wait for the "correct" solution later (sane routing and address
selection with multiple PA addresses on each interface)? I would
appreciate discussion either way--if the community starts down this path it
will be difficult to change. But a working solution is needed sooner
rather than later.
