multiple prefixes

[Frank Bulk]

I happen to be using two /64's in one non-end user VLAN and I've had no
issues thus far.

Subject: multiple prefixes

Hello,

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.

Regards,
David
