Figure 1-2 ICM-to-ICM Link Components
The ICM-to-ICM link shown in Figure 1-2 is a connection in one direction only.
It allows the Client ICM to send route requests to the Server ICM, but not the other
way around. It is possible to additionally reverse the roles of the ICMs as well, so
that each ICM can send route requests to each other. In this case, each ICM needs
an ICM Gateway and an INCRP NIC, as shown in Figure 1-3.
Figure 1-3 Bi-Directional ICM-to-ICM Link
INCRP supports direct connections between two ICMs only. ICMs that are not
directly connected with an ICM-to-ICM link cannot send each other route
requests through another ICM.
