In IS-IS, on a multi-access network segment, each router only forms an adjacency to the designated intermediate system (DIS). This means that they don't form adjacencies with every other router on the segment, only with the DIS. Regarding the DIS election process, a router with a higher priority value wins the election over a router with a lower priority value. Therefore, a router with a priority of 10 will win the DIS election over a router with a priority of 1.
In IS-IS, all routers establish a full neighbor adjacency with each other (unlike OSPF where routers only form a full neighbor adjacency with the DR/BDR).
