ϖNote: The Routing Timer values for individual WAN interfaces are set in separate windows. For more information, see the section in this chapter on the DECnet: WAN Configuration Dialog Box.
Max Addresses
This is the maximum number of node addresses allowed for this particular area. The default value for this parameter is 1023.
By limiting the number of addresses, a network administrator can limit the size of the internal routing table and the size of the routing messages sent to other routers.
Generally, all routers on the network should be consistent and use the same value for this parameter. This number should be at least as large as the number entered for this router’s node number.

Bridge Logical Diagram
Bridging operates on physical network addresses (such as Ethernet addresses), rather than logical addresses (such as DECnet addresses). From the standpoint of DECnet networking, router interfaces which are set to bridge DECnet between themselves appear as a single logical entity.
Thus, a router’s “DECnet Bridge Group” is made up of all of the physical network interfaces in a router which have been set to bridge DECnet.
