Ralph > The piece of network equipment that implements the relay agent routes, and that network equipment *might* also need a route. On the PE router implementing relay for DHCPv6-PD, it always needs add the associated route for the CE's network of delegated prefix. I can't see *might* here.

As Bernie wrote, relay agents don't route. The piece of network equipment that implements the relay agent routes, and that network equipment *might* also need a route. One of the issues we talked about in the dhc WG is that, in fact, a route might need to be installed in some equipment that is not on the client-server path. So, yeah, perhaps s/provider edge router/some network equipment/ or even s/provider edge router/the network/ - Ralph > > We are not a provider.
