Topology Considerations
An Expand-over-SNA network must be configured as a logical fully connected mesh. In
a single-line path configuration, you configure one Expand-over-SNA line-handler
process for each destination node in the network. In a multi-CPU configuration, you
configure multiple Expand-over-SNA line-handler processes, usually in separate
processors, for each destination node in the network. In a multi-line path configuration,
you configure a path that consists of multiple lines between the source and destination
nodes.
In Figure 11-2, a single-line path is configured between node \A and node \C; a multi-
CPU path that consists of two path is configured between node \A and node \B; and a
multi-line path that consists of three lines is configured between node \B and node \C.
