Configuring frame-relay without sub-interfaces

Description: Configure frame-relay without using sub-interfaces. This configuration example uses full mesh topology.


Note that on a frame-relay network without sub-interfaces, the LMI-type is automatically detected. Similarly, PVC DLCIs are learned through CMS status messages. There is no need to specify the same explicitly. On the otherhand, in a FR network with point-to-point sub-interface configurations, you need to specify the interface-dlci number. 

Instructions:

IP Address Assignment Table

Device Interface
Venus-S0 192.160.1.1/24
Jupitor-S0 192.160.1.2/24
Saturn-S0 192.160.1.3/24

1. Specify frame-relay on S0 of Venus

2. Specify frame-relay on S0 of Saturn

3. Specify frame-relay on S0 of Jupitor
