[PE-bgp] peer 2.2.2.9 as-number 100
[PE-bgp] peer 2.2.2.9 connect-interface loopback 1
[PE-bgp] ipv4-family vpnv4
[PE-bgp-af-vpnv4] peer 2.2.2.9 enable
[PE-bgp-af-vpnv4] quit
[PE-bgp] quit
Step 5 Configure the SPE.
# Configure the VPN instance.
[SPE] ip vpn-instance vpna
[SPE-vpn-instance-vpna] route-distinguisher 200:1
[SPE-vpn-instance-vpna] vpn-target 1:1
[SPE-vpn-instance-vpna] quit
# Specify the UPE for the SPE.
[SPE] bgp 100
[SPE-bgp] ipv4-family vpnv4
[SPE-bgp-af-vpnv4] peer 1.1.1.9 upe
# Advertise the default route of the VPN instance to the UPE.
[SPE-bgp-af-vpnv4] peer 1.1.1.9 default-originate vpn-instance vpna
[SPE-bgp-af-vpnv4] quit
Step 6 Verify the configuration.
After the configuration, CE1 has no route to the network segment of the interface on CE2, but
it has a default route with the next hop being UPE. CE2 has a BGP route to the network segment
of the interface on CE1. CE1 and CE2 can ping each other.
