branch router

4. All branch routers list the same central routers in their central router fields

5. Central routers have 0 in their central router fields

FIGURE 14.3-1. Example Branch Routers Network

C1 (central router) could be a CR800 with RF401 and RS-232 cable to a PC

running LoggerNet. The nodes beginning with “B” could be CR800 branch

routers with RF401s (listing 4094 and 1 as central routers). The nodes

beginning with “L” could be CR800 leaf-nodes with RF401s (or CR206s).

Leaf nodes are not routers and have no central router lists.

In a network without branch routers, every router is essentially a ‘central

router’ since every router strives to know the neighbor lists of all the routers in

the network.

The Connect Screen Status Table tool can be used to input the list of network

central routers to the branch routers. Notice in the example that LoggerNet is

included as a central router. LoggerNet does not have the ability to be a

branch router (can’t list the central routers), and so must always be listed with

any central routers and, according to the rules, be contiguous with the other

central routers.
