# Configure a default route from the agent server of the VPN to the Internet. The next hop is P.
Specify the address of the next hop as a public network address. That is, add the keyword
public
to the right of the next hop address in the command.

ip route-static vpn-instance vpn1 0.0.0.0 0 100.1.1.2 public
NOTE
If the CE and PE are connected through the Ethernet, you must specify the next hop.
# Configure a static route from the Internet to the agent server. The next hop is CE1.
[PE1]
ip route-static 100.3.1.1 24 vpn-instance vpn1 10.1.1.1
# Advertise the static route from PE1 to the agent server to the Internet through IGP.

# Configure the agent server. Set the IP address of the agent server to 100.3.1.1/24. Specify CE1
as the default gateway (100.3.1.2/24) of the agent server. In addition, the agent software should
be run on the agent server.
Step 6
Verify the configuration.
Run the
display ip routing-table vpn-instance
command on PE1, and you can see that a default
route exists in the routing table of VPN 1. The next hop address is 100.1.1.2 and the outgoing
interface is Vlanif10.
