Step 4 Configure the VPN instances on the PE devices and connect the CE with the PE2 and PE3.
# Configure the PE1.
[PE1] ip vpn-instance vpn1
[PE1-vpn-instance-vpn1] ipv4-family
[PE1-vpn-instance-vpn1-af-ipv4] route-distinguisher 100:1
[PE1-vpn-instance-vpn1-af-ipv4] vpn-target 111:1
[PE1-vpn-instance-vpn1-af-ipv4] quit
[PE1-vpn-instance-vpn1] quit
# Configure the PE2.
[PE2] ip vpn-instance vpn1
[PE2-vpn-instance-vpn1] ipv4-family
[PE2-vpn-instance-vpn1-af-ipv4] route-distinguisher 100:2
[PE2-vpn-instance-vpn1-af-ipv4] vpn-target 111:1
[PE2-vpn-instance-vpn1-af-ipv4] quit
[PE2-vpn-instance-vpn1] quit
[PE2] interface gigabitethernet2/0/0
[PE2-GigabitEthernet2/0/0] ip binding vpn-instance vpn1
[PE2-GigabitEthernet2/0/0] ip address 10.1.1.2 30
[PE2-GigabitEthernet2/0/0] quit
# Configure the PE3.
[PE3] ip vpn-instance vpn1
[PE3-vpn-instance-vpn1] ipv4-family
[PE3-vpn-instance-vpn1-af-ipv4] route-distinguisher 100:3
[PE3-vpn-instance-vpn1-af-ipv4] vpn-target 111:1
[PE3-vpn-instance-vpn1-af-ipv4] quit
[PE3-vpn-instance-vpn1] quit
[PE3] interface gigabitethernet2/0/0
[PE3-GigabitEthernet2/0/0] ip binding vpn-instance vpn1
[PE3-GigabitEthernet2/0/0] ip address 10.2.1.2 30
[PE3-GigabitEthernet2/0/0] quit
Step 5 Import VPN routes on all PEs. Set up EBGP peer between PE2 and CE, between PE3 and CE.
# Configure the PE1.
[PE1] bgp 100
[PE1-bgp] ipv4-family vpn-instance vpn1
[PE1-bgp-vpn1] import-route direct
[PE1-bgp-vpn1] quit
# Configure the PE2.
[PE2] bgp 100
[PE2-bgp] ipv4-family vpn-instance vpn1
[PE2-bgp-vpn1] peer 10.1.1.1 as-number 65410
[PE2-bgp-vpn1] quit
# Configure the PE3.
[PE3] bgp 100
[PE3-bgp] ipv4-family vpn-instance vpn1
[PE3-bgp-vpn1] peer 10.2.1.1 as-number 65410
[PE3-bgp-vpn1] quit
# Configure the CE.
