procedure for each configuration
Configuring OSPF on the
Point-to-Multipoint
Network.
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.
