z
A static route configured for a VPN instance does not take effect if you configure the next hop
address of the route as the IP address of a local interface (such as Ethernet interface, VLAN
interface).
z
If the default static route preference is not configured, the preference of a newly defined static route
adopts the system default preference value, which is 60. A customized default static route
preference has no effect on existing static routes.
z
Static routes can be controlled selectively by using routing policies according to the tag values set
for static routes.
z
The ip route-static command defines a default route if both the destination address and the mask
are set to 0.0.0.0.
Configuring to Use RIP between a MCE and a PE
When configuring to use RIP between a MCE and a PE, you need to configure the RIP processes to be
bound to the VPN instances and manually import the VPN routes in the site maintained by the MCE
device to the routing table of the PE.
Follow these steps to enable RIP for a VPN instance:

Configuring to Use OSPF between a MCE and a PE
When configuring to use OSPF between a MCE and a PE, you need to configure the OSPF processes
to be bound to VPN instances and router IDs; you also need to manually import the VPN routes in the
site maintained by the MCE device to the routing table of the PE.
Follow these steps to configure OSPF between a MCE and a PE:
