One Comment on “which device represents the pseudo-node?

  1. azman says:

    A pseudonode is a logical representation of the LAN which is generated by a Designated Intermediate System (DIS) on a LAN segment.

    On broadcast multi-access networks, a single router is elected as the DIS. There is no backup DIS elected. The DIS is the router that creates the pseudonode and acts on behalf of the pseudonode.
