5. Configure an MP-IBGP peer relationship between PEs
# Configure PE 1.
[PE1] bgp 100
[PE1-bgp] peer 3.3.3.9 as-number 100
[PE1-bgp] peer 3.3.3.9 connect-interface loopback 0
[PE1-bgp] ipv4-family vpnv4
[PE1-bgp-af-vpnv4] peer 3.3.3.9 enable
[PE1-bgp-af-vpnv4] quit
[PE1-bgp] quit
# Configure PE 2.
[PE2] bgp 100
[PE2-bgp] peer 1.1.1.9 as-number 100
[PE2-bgp] peer 1.1.1.9 connect-interface loopback 0
[PE2-bgp] ipv4-family vpnv4
[PE2-bgp-af-vpnv4] peer 1.1.1.9 enable
[PE2-bgp-af-vpnv4] quit
[PE2-bgp] quit
After completing the configuration, issue the display bgp peer command or the display bgp vpnv4
all peer command on the PEs. The output shows that BGP peer relationship has been established
between the PEs, and has reached the Established state.
[PE1] display bgp peer

6. Verify your configurations
Issue the display ip routing-table vpn-instance command on the PEs. The output shows the routes
to the CEs. The following takes PE 1 as an example:
[PE1] display ip routing-table vpn-instance vpn1
