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?

This is being blocked by a number of parties at the IETF because of religious systemic antipathy towards DHCPv6. Nick

I don't know about brocade, but here's what I see in Junos and IOS... ....dhcpv6 relay binding seen... {master:0} agould@eng-lab-5048-2> show dhcpv6 relay binding routing-instance three Prefix Session Id Expires State Interface Client DUID 2699:2699:0:7::100/128 199 2591002 BOUND irb.26 LL_TIME0x1-0x1861ed8c-e8:03:9a:eb:0d:21 ....that same binding above is seen as a /128 route of type access-internal... {master:0} agould@eng-lab-5048-2> show route table three.inet6.0 2699:2699:0:7::100/128 three.inet6.0: 16 destinations, 38 routes (16 active, 0 holddown, 0 hidden) + = Active Route, - = Last Active, * = Both 2699:2699:0:7::100/128 *[Access-internal/12] 1w5d 03:19:06 > to fe80::fd61:6bfe:da75:4801 via irb.26 --------------------------------------------------------------------------- ....dhcpv6 relay binding seen... eng-lab-3600-1#sh ipv6 dhcp relay binding vrf three Prefix: 2699:2699:FE00:30::/64 (Vlan26) DUID: 00030001B0B2DCCB1D1E IAID: Unknown lifetime: 2592000 expiration: 06:21:48 CDT Oct 25 2017 ....that same binding above is seen as a /64 route of type static... eng-lab-3600-1#sh ipv6 route vrf three 2699:2699:FE00:30::/64 Routing entry for 2699:2699:FE00:30::/64 Known via "static", distance 1, metric 0 Route count is 1/1, share count 0 Routing paths: FE80::B2B2:DCFF:FECB:1D1E, Vlan26 Last updated 3w4d ago eng-lab-3600-1#sh ipv6 route vrf three static IPv6 Routing Table - three - 18 entries Codes: C - Connected, L - Local, S - Static, U - Per-user Static route B - BGP, R - RIP, I1 - ISIS L1, I2 - ISIS L2 IA - ISIS interarea, IS - ISIS summary, ND - ND Default, NDp - ND Prefix DCE - Destination, NDr - Redirect, O - OSPF Intra, OI - OSPF Inter OE1 - OSPF ext 1, OE2 - OSPF ext 2, ON1 - OSPF NSSA ext 1 ON2 - OSPF NSSA ext 2 ....
