Introduction [RFC5838] defined the "OSPFv3 Instance ID Address Family Values" registry for the purpose of mapping OSPFv3 Instance IDs to different address families. The following table lists the value ranges as currently allocated. +---------------------------+-------------------+-------------------+ | Instance ID Range | Description | Assignment Policy | +---------------------------+-------------------+-------------------+ | Instance ID # 0 - # 31 | IPv6 unicast AF | Already Assigned | | Instance ID # 32 - # 63 | IPv6 multicast AF | Already Assigned | | Instance ID # 64 - # 95 | IPv4 unicast AF | Already Assigned | | Instance ID # 96 - # 127 | IPv4 multicast AF | Already Assigned | | Instance ID # 128 - # 255 | Unassigned | Standards Action | +---------------------------+-------------------+-------------------+ In some networks additional OSPFv3 instances may be required to operationally identify specific applications. 2. OSPFv3 Instance ID Address Family Values Registry Update The IANA "OSPFv3 Instance ID Address Family Values" registry must be updated as follows: +---------------------------+-------------+-----------------------+ | Instance ID Range | Description | Assignment Policy | +---------------------------+-------------+-----------------------+ | Instance ID # 128 - # 191 | Unassigned | Standards Action | | Instance ID # 192 - # 255 | Unassigned | Private Use [RFC5226] | +---------------------------+-------------+-----------------------+ 3. IANA Considerations This document requests the modification of the "OSPFv3 Instance ID Address Family Values" registry as described in Section 2. 4. Security Considerations This document modifies the assignment policy of an IANA registry defined in [RFC5838]. It does not introduce any new security issues.
