IISP Routes

Note

Dotted lines in the diagrams below represent one-way IISP routes to the devices
pointed to by the arrowheads. Each route is defined on the device from which the
dotted line originates.

IISP Routing Example Two

A second IISP device (Switch D) is added behind Switch A. If Switch D also needs to reach Switch C for LANE
support, additional IISP routes must be defined between Switches D and C, B and D, and A and D. Figure 5-2 shows
the typical “route to every point reached” IISP topology.
