Run the display bgp vpnv4 all peer command on the PEs, and you can find that the MP-IBGP
adjacency is in Established state. Take PE1 for example.

Step 4 Create VPN instances and set up EBGP adjacencies.
Create VPN 1 on the PEs and bind VPN 1 to the interfaces connected to CEs. Set up EBGP
adjacencies between PE1 and CE1 and between PE2 and CE2 to import routes of the CEs to the
PEs. The detailed configuration is not mentioned here.
After the configuration, run the display ip vpn-instance command on the PEs, and you can find
VPN 1 is displayed in the VPN-Instance Name field.
Take PE1 for example.
[PE1] display ip vpn-instance
Total VPN-Instances configured : 1
VPN-Instance Name RD Creation Time
vpn1 100:1 2010/01/16 17:30:42 UTC-0

Run the display bgp vpnv4 all peer command on the PEs, and you can see that the IBGP and
EBGP adjacencies are in Established state.
Take PE1 for example.
<PE1> display bgp vpnv4 all peer
BGP local router ID : 1.1.1.1
Local AS number : 100
Total number of peers : 2 Peers in established state : 2
Peer V AS MsgRcvd MsgSent OutQ Up/Down State PrefRcv

Step 5 Configure the static route to enable VPN users to access the public network.
# Add a default route on CE1 with the next hop being PE1.
<CE1> system-view
[CE1] ip route-static 0.0.0.0 0 10.1.1.2
# Configure PE1.
