Just wondering from those in the know, whether it's best practice to implement public or private IP's for the PE-to-CE link. What's everyone using and why?
Best practice is to use public IP for the PE-CE link and then you admin the CE using that address. If you have a serial interface you can do this with a /32 routed towards the physical interface and use unnumbered/loopback, otherwise you have to use /30 or /31.
Using RFC1918 space creates huge potential of overlaps with customers, and a nightmare for management if you want your CE range to be unique per VPN, how are you going to reach your CEs via SNMP etc?
