hey,
So I'd say there is equipment out there that works, as expected, but as seen in this thread, plenty of equipment that doesn't.
Latest OpenWrt releases include https://github.com/sbyx/odhcpd as DHCPv4/6 server. This enables hierarchical PD on these platforms, ie. subdelegate /64s from the /56 PD prefix you received from SP.
It's not the most configurable thing at this point but it does the job.
If your SP is giving you a /56, you should complain and ask for a proper /48.
Especially if you’re doing any real hierarchical PD.

Or you just don't do heirarchial routing / PD inside the site. It isn't needed. 65000 intra site routes isn't that hard handle nor is 65000 PD's for the border routers. -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@isc.org
