As replied in a separate message (not from me), BSDs separate the processing of an RA prefix wrt address configuration from the processing of the prefix wrt on-link determination. Specifically, A. if a BSD host receives an containing prefix P/x with the L flag on, it installs a direct route P/x to the receiving interface, indicating Neighbor Discovery (NS/NA) is necessary for destinations covered by the prefix. B. if a BSD host receives an containing prefix P/x with the A flag on, it configures the interface with the address P:I (I is some interface identifier) A and B are done separately and independently, and processing B does not involve any direct route creation. So, if a BSD host receives a prefix P/x with the L flag off and A flag on, it configures the receiving interface with the address P:I/128. Since there is no direct route for the prefix P/x, any packet to destinations covered by the prefix (except P:I) will be sent to the default router (if any). > Unless an IETF standard has specific RFC 2119 languge in it, your milage > can vary. That is true in general, and it's not specific to RFC2461 (or 2461bis). The semantics of the L bit might be clearer, but I personally believe the L bit processing is widely interpreted as described above. JINMEI, Tatuya Communication Platform Lab.
