Multihoming - Resilience or Independence

Just a short comment from the RIR perspective.

The issues brought up in this discussion are questions that the RIPE NCC 
hostmasters are confronted with daily in the IP request handling.

Requesters who wish to multi-home (for one reason or the other) often ask 
the hostmasters for advise on whether to do it with PI address space or by 
having their upstream announcing a more specific route within a PA 
aggregate (which is then also separately announced through a second upstream).

Rather than the RIRs giving advise on these operational matters, we think 
it would be appropriate and helpful if these recommendations would come 
from the ISP community.

A few BCPs or guideline documents would be useful to point these requesters 
to.
Could this be an initiative for the routing-wg?

Kind regards,
