About Route Determination
The node prefixes, port prefixes, and port addresses configured on network nodes are
used to determine the route for a given SVC. A “best match” hierarchy determines the
route, starting from the left-most digit of the called party address.
Keep in mind that you use node prefixes to summarize the common address parts of
the node. For example, if all addresses on the node contain the digits 15085551, you
would define this as the node prefix. To allow for address routing, node prefixes
should be unique to a switch; if not, the switch has to perform subsequent matching to
find a route to the destination.
The following example shows three nodes configured with a combination of native
E.164 node prefixes, port prefixes, and port addresses:
