Setting Up Routes

Switch Administration

IISP routes between A, B, and C can be defined by

11:22: + group identifier byte

Collectively, groups A, B, and C represent the super-group "A-B-C." Any group from outside A-B-C can define a route to A-B-C by using just 11:22.

11:22:33
11:22:33:00	A
11:22:33:01
11:22:55	11:22:44

Routing Loops

Be careful not to create "ambiguous routes" (that is, routes defined by too few bytes). For instance, if a route is defined within the super-group A-B-C by specifying 11:22 as the destination, a routing loop is created. An additional byte is necessary to specify to which group (A, B, or C) the destination belongs.
