Configuring X.25

Scenario 3: Fully

Meshed Topology

A fully meshed topology consists of bridge/routers that are connected 
directly to every other bridge/router. Between each bridge/router, you 
must order a Frame Relay circuit from the service provider.

No configuration is required for this scenario.

Configuring X.25

This section describes two X.25 scenarios:

■

Scenario 1: Multiple Destinations, Nonmeshed

■

Scenario 2: Fully Meshed Topology

See 

Using Enterprise OS Software 

to modify the default DTE profile, to 

create a permanent virtual circuit (PVC), or to configure connection 
services.
