# 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.
<PE1> system-view
[PE1] 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.
[PE1] ospf 1
[PE1-ospf-1] import-route static
# 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.
