# Configure VPN instances.
[SPE] ip vpn-instance vpna

[SPE-vpn-instance-vpna-af-ipv4] quit
[SPE-vpn-instance-vpna] quit
# Specify a 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 VPN instances to 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 does not have a route to the network segment of the interface on
CE2, but has a default route with the next hop to UPE. The CE2 has the route to the network
segment of the interface on CE1. Therefore, CE1 and CE2 can ping through each other using
the ping ip-address command.
