[Kea-users] Assigning unique /64 to each CPE for IA_NA

[Xuo Guoto]

Hello Kea list,

I am trying to configure kea-ipv6 in a BNG context where kea will be responsible for providing IP address for WAN (IA_NA) and for IA_PD. There is a requirement that when assigning IA_NA each Residential Gateway be given an IP address from a separate /64 prefix.

For example RIPE BCOP-690 section 4.1.1 says:

<quote>
Using a /64 prefix from a dedicated pool of IPv6 prefixes is the most common scenario and currently the best practice. A separate block of IPv6 space is allocated for the WAN links to the end customer CPEs, so that when CPE connects to the network and performs router discovery, a /64 prefix is used to number both ends of the connection.</quote>

How such a configuration be provided in kea? From what I have seen if a /48 prefix is used in pool, kea will try to allocate single /128 to each CPE, and pd-pools are for IA_PD.

Thanks for your help!

X.
