| Designated Intermediate System (DIS) is elected and will conduct the flooding over the media. The DIS is analogous to the designated router in Open Shortest Path First (OSPF) Protocol, even though the details including election process and adjacencies within a multi-access media differ significantly. The DIS is elected by priority. The highest priority becomes the DIS. This is configurable on an interface basis. In the case of a tie, the router with the highest SNPA (MAC) address will become the DIS. |
