III. Configuration procedure
The following are the configuration introduction to PE, CE and P switches.
1) Configure CE1.
Configure CE1 and PE1 as EBGP neighbors, import direct-connect routes and static
routes to import intra-CE1 VPN routes into BGP and advertise to PE1.CE1connects to
PE1 through interface Gigabitethernet 2/1/1.
