Configuring Expand-Over-ATM Lines

Topology Considerations

In a single-line configuration, you configure one Expand-over-ATM line-handler

process for each path to an adjacent node. In a multi-CPU path configuration, you

configure multiple Expand-over-ATM line-handler processes, usually in separate

processors, for each path to an adjacent node. In a multi-line path configuration, you

configure a path that consists of multiple lines between adjacent nodes.

In Figure 9-2, a single-line path is configured between node \A and node \B; a multi-

CPU path that consists of two paths is configured between node \A and node \C; and a

multi-line path that consists of three lines is configured between node \C and node \D.
