Step 3 Establish the MP-IBGP peer relationship between the PEs.
# Configure PE1.
[PE1] bgp 100
[PE1-bgp] peer 3.3.3.9 as-number 100
[PE1-bgp] peer 3.3.3.9 connect-interface loopback 1
[PE1-bgp] ipv4-family vpnv4
[PE1-bgp-af-vpnv4] peer 3.3.3.9 enable
[PE1-bgp-af-vpnv4] quit
[PE1-bgp] quit
# Configure PE2.
[PE2] bgp 100
[PE2-bgp] peer 1.1.1.9 as-number 100
[PE2-bgp] peer 1.1.1.9 connect-interface loopback 1
[PE2-bgp] ipv4-family vpnv4
[PE2-bgp-af-vpnv4] peer 1.1.1.9 enable
[PE2-bgp-af-vpnv4] quit
[PE2-bgp] quit
After the configuration, run the display bgp peer command or the display bgp vpnv4 all peer
command, you can see that the BGP peer relationship is set up between the PE and the CE, and
the peer status is Established.
