Requirements 3/3 RQ 7: Address Duplication Considerations In the case that collision occurs, the configuring node MUST inform the owner (or simultaneously configuring node) that the configuration attempt has occurred. In [RFC 2462], this occurs through the sending of the original Neighbor Solicitation packet. Additionally, if intermediate neighbor cache state on peers has been created, it MUST be repaired in conformance to RQ2. RQ 8: Layer 2 Considerations Generally, address duplication is happened to the same Interface ID which is composed of 48bit/64bit MAC address. Therefore, when same MAC address is existed in the same link, one of these nodes can not make its IPv6 address using address autoconfiguration mechanism. At this case, all nodes MUST be allowed to generate new addresses by another mechanism. It should be clarified that the mechanisms should be more discussed in the near future. |
