[rpd] New Policy Proposal Received - "Multihoming not required for ASN (AFPUB-2019-ASN-DRAFT01)"

[Fernando Frediani]

Hello

The point about not requiring Mulihoming for requesting an ASN is much 
simpler than it may look I believe. I mean I agree with the points of 
the author in the sense that some things used to be taken in account 
before are not relevant anymore and the policy can be adjusted to 
reflect that and make the things more smooth in order that should an 
entity feels like becoming an ASN there are no unnecessary barriers like 
this one.

Regards
Fernando
