Is anyone doing two or more prefixes per VLAN? Specifically I'm toying with the idea of having a provider dependent (PD) prefix which uses the privacy options (RFC 3041/4941) for external surfing, and a ULA-based prefix for internal traffic (using EUI for better logging).
From what I could find, there aren't any RA options to specify whether privacy options should be used on a per prefix basis. You'd have to use DHCPv6, with IA_TA for privacy-desired prefixes, and IA_NA for the ULA prefixes. (Of course ISC DHCPd doesn't support sending out multiple prefixes as of the current 4.2.x series.)
Has anyone done this, or considered doing it? Pros/cons?
Thanks for any info.
