transmit rate
Configuring OSPF Sham Link
The sham link is considered an OSPF intra-area route. It is used to ensure that the VPN traffic is
transmitted over the backbone instead of the backdoor link between two CEs.
The source and destination addresses of the sham link must be loopback interface addresses with
32-bit masks. Besides, the loopback interfaces must be bound to the VPN instances and be advertised
through BGP.
Configuration Prerequisites
Before configuring OSPF sham link, be sure to configure OSPF in the LAN where CEs reside
Configuring a Loopback Interface

Advertising Routes of a Loopback Interface
Follow these steps to advertise routes of a loopback interface:
To do...
Enter system view
Enter BGP view
Use the command...
