details are not mentioned here.
# After the configuration, run the display ip vpn-instance verbose command on PEs, and you
can view configuration results of VPN instances.
For example, information about PE1 is displayed as follows:
<PE1> display ip vpn-instance verbose
Total VPN-Instances configured : 1
VPN-Instance Name and ID : vpn1, 1

Up time : 0 days, 01 hours, 56 minutes and 16 seconds
Route Distinguisher : 100:1
Export VPN Targets : 1:1
Import VPN Targets : 1:1
Label policy : label per route
Log Interval : 5

Step 5 Configure EBGP between PEs and CEs to import VPN routes.
# Configure CE1.
# Enable BGP, specify PE1 and PE2 as EBGP peers, and import direct routes.
[CE1] bgp 65410
[CE1-bgp] peer 10.1.1.2 as-number 100
[CE1-bgp] peer 10.2.1.2 as-number 100
[CE1-bgp] import-route direct
[CE1-bgp] quit
# Configure PE1.
# Enable BGP.
