Establish EBGP peer relationships between PEs and CEs, and redistribute VPN routes into BGP:
# Configure CE 1.
[CE1] bgp 65410
[CE1-bgp] peer 10.1.1.2 as-number 100
[CE1-bgp] address-family ipv4 unicast
[CE1-bgp-ipv4] peer 10.1.1.2 enable
[CE1-bgp-ipv4] import-route direct
[CE1-bgp-ipv4] quit
[CE1-bgp] quit
# Configure the other three CEs in the same way that CE 1 is configured. (Details not shown.)
# Configure PE 1.
[PE1] bgp 100
[PE1-bgp] ip vpn-instance vpn1
[PE1-bgp-vpn1] peer 10.1.1.1 as-number 65410
[PE1-bgp-vpn1] address-family ipv4 unicast
[PE1-bgp-ipv4-vpn1] peer 10.1.1.1 enable
[PE1-bgp-ipv4-vpn1] import-route direct
[PE1-bgp-ipv4-vpn1] quit
[PE1-bgp-vpn1] quit
[PE1-bgp] ip vpn-instance vpn2
[PE1-bgp-vpn2] peer 10.2.1.1 as-number 65420
[PE1-bgp-vpn2] address-family ipv4 unicast
[PE1-bgp-ipv4-vpn1] peer 10.2.1.1 enable
[PE1-bgp-ipv4-vpn2] import-route direct
[PE1-bgp-ipv4-vpn2] quit
[PE1-bgp-vpn1] quit
[PE1-bgp] quit
# Configure PE 2 in the same way that PE 1 is configured. (Details not shown.)
After completing the configurations, execute the display bgp peer ipv4 vpn-instance command on
the PEs. The output shows that a BGP peer relationship has been established between a PE and a
CE and has reached the Established state. Take PE 1 as an example:
[PE1] display bgp peer ipv4 vpn-instance vpn1
BGP local router ID: 1.1.1.9
Local AS number: 100

Establish an MP-IBGP peer relationship between PEs:
# Configure PE 1.
