Scenario 3: Fully A fully meshed topology consists of bridge/routers that are connected Meshed Topology 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
