Configure Frame Relay
over Other Protocols
Frame Relay over IP IP networks are used to carry the Frame Relay data to interconnect the Frame
Relay networks. In the technique of Frame Relay over IP, a GRE tunnel is
established between the Frame Relay networks at both ends of IP, and the Frame
Relay data are carried over IP. The application of Frame Relay over IP is illustrated in
the following figure:

Configure Frame Relay over IP
1 Configure tunnel interface
Create a tunnel interface in all views or enter the tunnel interface view to perform
the following configurations.
Table 311 Configure a tunnel interface
Operation
Create a tunnel interface
Specify a source address for the tunnel interface
Specify a destination address for the tunnel interface
In addition, the user can make the configurations, such as packet mode, ID
keyword, for the tunnel interface. The tunnel interface configuration details will
not be covered here. Please read the related chapters in Operation manual - VPN
for reference.
2 Configure Frame Relay Switching
Enable Frame Relay switching in system view and configure Frame Relay switched
routes in serial interface view.
Table 312 Configure Frame Relay switching
Operation
Enable Frame Relay switching
Configure a Frame Relay switched route
If the specified tunnel interface does not exist when implementing configuration,
the system will automatically create a tunnel interface. However, the Frame Relay
switched route can take effect only after the source address, destination address,
and IP address have been configured for the tunnel interface.
