I. Creating static route
If you select static route mode for CE-PE route switching, you should then configure a
private static route pointing to PE on CE.
Perform the following configuration in the system view.

By default, the preference value for a static route is 60. You can also specify preference
for a static route.
II. Configuring RIP
If you select RIP mode for CE-PE route switching, you should then configure RIP on CE.
For detailed RIP configuration steps, see the RIP section in this guide
III. Configuring OSPF
If you select OSPF mode for CE-PE route switching, you should then configure OSPF
on CE. For configuring OSPF, see the routing protocol section of this guide.
You must configure OSPF multi-instance to isolate services of different VPNs on CE
router, which is now called Multi-VPN-Instance CE.
You can bind OSPF procedures with VPN with the following command in OSPF view.

IV. Configuring EBGP
If you select BGP mode for CE-PE route switching, you should then configure EBGP
peer, import direct-connect route, static route and other IGP routes, for BGP to
advertise VPN routes to PE.
