Alias and Call Routing Configuration: Alias Configuration Examples

Link-to-Link Call Routing

Link-to-link call routing lets users route all SVC calls coming in on one X.25 link to another X.25 link. By using X.25 link-to-link call routing, it is now possible to create a default route for all calls from a specified X.25 link. The alias for the default link-to-link route can route all calls destined for the same link. On previous versions of AI296, users had to create an alias for each unique called address.

In Figure 8-6, NE1 and NE2 place calls to NE3, NE4, and other elements on the X.25 network. Aliases route calls from NE1 and NE2 to the network elements. A link-to-link call route exists between links 1 and 2, and between links 3 and 4. An incoming X.25 SVC call from NE1 that does not match an alias in the table would be routed to link 2, and an incoming X.25 SVC call from NE2 that does not match an alias in the table would be routed to to link 4.

Important: The link-to-link call alias must be at the end of the alias list. If the link-to-link alias is above an actual destination alias, an X.25 SVC call will be processed by the default link-to-link alias.
