Food for thought: - ASNs can be reused at different locations by IXPs, barring perhaps certain business or administrative reasons. Ask Equinix. - For IXPs that already have 16-bit ASNs for route servers, this saves additional allocations from RIRs and mitigates concerns for the IXP getting potentially a 32-bit ASN, thus having trouble with BGP communities as described. Having a single ASN may raise other issues but it is an option. - I believe it would help if RIRs reserved 16-bit ASNs in addition to IPv4 micro allocations for IXPs, until a formal solution can be finally found about the 32-bit ASN BGP communities issue.
