DHCPv6-PD -> Lack of route injection in RFC

Fri Sep 22 21:46:54 UTC 2017

I know of several methods all flawed in some ways. There seems to be no
progress in this obvious lack of a solid easy way to inject routes to match
DHCP-PD.

We use ExaBGP to inject routes via BGP that matches the configuration that
our DHCP server has. But this is non standard and clumsy to implement. Does
not work with all CPE routers either.

Which method would you recommend as an alternative?

This method is lacking because you might have several routers eg. using
VRRP and the backup router will not learn anything from a relay on the
primary.

I am running into venders that do not support injection of a delegated
route when operating as a DHCPv6 relay (or server for that matter).
Brocade supports this, but I am not finding this as part of any of the
RFC's.  This is to deliver home ISP service, so it is very important or
return packets won't go to the client unless the route is manually added as
a routing protocol is not an option.  There should be a MUST activity for
this somewhere.

Anyone know what gives?
