OSPF Configuration Example

Configuring OSPF on the Point-to-Multipoint Network.

This section describes several different configurations of OSPF with a suggested procedure for each configuration

The configuration for this example includes the following features:

■Router A communicates with Router B through DLCI 101, communicates with Router C through DLCI 102, and communicates with Router E through DLCI 103.

■Router B communicates with Router A through DLCI 201 and communicates with Router C through DLCI 202.

■Router C communicates with Router A through DLCI 301 and communicates with Router B through DLCI 302.

■Router D communicates with Router E through DLCI 401.

■Router E communicates with Router A through DLCI 501 and communicates with Router D through DLCI 502.
