Does anyone have tips for getting a juniper SRX branch office router to relay prefix delegation requests to NIOS and what the config in NIOS has to look like?

The config in NIOS is easy to accomplish and can be done leveraging the "Add Range" wizard under a v6 network:
Unfortunately I have not tested the delegation on my SRX so perhaps someone who has will have some comments or this thread on Juniper's site may be of help:

Thanks. I got that part. I'm not seeing how infoblox knows that when it receives a DHCPv6-PD request relayed from a certain router, that it should use a certain pool for the PD. I'd like to have /48s aggregated at each smaller POP and do /56 PD. The customer's router should be using RA to discover the router's IP address. In IPv4, it's easy to match a pool to a DHCP request since the DHCP request is relayed with a source address in the network block that contains the pool. I don't think this is the case with IPv6. If I have this wrong, can some one let me know?

Infoblox DHCPv6 adheres to RFC 3633 and leverages an IA_PD for the association with the client/requestor. With DHCPv6 the DHCP request may contain a preference for the prefix in the IA_PD or no preference... this is up to the client. Once you have created the prefix delegation under a v6 network in Infoblox you can also created "fixed addressing" assignments within the prefix delegations that will match specific prefixes to a client based on their DUID.
Hopefully that will help you on the right track!

Just to add some closure to this thread. I got around to asking Infoblox for help setting this up and I was told the NIOS doesn't yet support DHCPv6 Prefix Delegation.
