Additonal notes
Protocol processing is done on a per link basis, not per subnet, which means you need only a single adjacency per link even if there are multiple IPv6 subnets on the link. This eliminates the requirement for matching subnet mask to form an adjacency.
Link LSA—This LSA has local scope and does not extend beyond the link it is associated with. The purpose of a link LSA is to provide the router’s IPv6 link-local address to neighbors, inform other routers of the associated IPv6 prefixes available on the link, and provide information to the Networks. It enables the router to assert a collection of options bits in the network LSA to be originated for the link.
