Need a DHCPv6 route option?
Unfortunately the anti-DHCP crowd hasn't budged, no matter how many operators have told them that they cannot manage an IPv6 network with the current state of the protocol.
FYI, the operators suffering from a lack of feature of some standard are free to have an agreement on how to use the private use part of a number range in the standard controlled by someone else. It is legal, harmless and IETF did so, for example, to map IPv6 multicast addresses to local (that is, not assigned by IEEE and for private use) Ethernet group MAC addresses in section 7 of rfc2464. Thus, interested operators can have an agreement to use some private use option values (224-254) of DHCPv6 for the route option. Moreover, the agreement can be published as a NANOG/RIPE/APRICOT/... recommendation or a some (newly formed) forum standard. Then, some implementers are happily follow the recommendation/standard in addition to IETF standards. At least, ISC has done so, already. https://www.isc.org/blogs/routing-configuration-over-dhcpv6-2/ The presented examples use values 242 for NEXT_HOP and 243 for RTPREFIX option codes. Don't you want to increase the number of operators endorsing the private assignments? Masataka Ohta
