Configuring Frame Relay Interfaces for the XP
allow you to route critical packet transmissions from host to peer without concern for network
congestion significantly slowing, let alone interrupting, your communications. PVCs are the most
prevalent type of circuit used today and are similar to dedicated private lines in that you can lease
and set them up through a service provider.
In a corporate setting, network administrators can use PVCs in an internal network to set aside
bandwidth for critical connections, such as videoconferencing with other corporate departments.
Note: Interfaces configured with PVCs do not support LSNAT and VRRP.
Configuring Frame Relay Interfaces for the XP
This section provides an overview of configuring a host of WAN parameters and setting up WAN
interfaces. When working in the Frame Relay protocol environment, you must first define the type
and location of the WAN interface. Having established the type and location of your WAN
interfaces, you need to (optionally) define one or more service profiles for your WAN interfaces,
then apply a service profile to the desired interface(s). An example of this process is covered in
Frame Relay Port Configuration on page 499.
Defining the Type and Location of a Frame Relay and VC Interface
To configure a frame relay WAN port, you need to first define the type and location of one or more
frame relay WAN ports or virtual circuits (VCs) on your XP. The following command line displays
a simplified example of a frame relay WAN port definition:
Note: If the port is a HSSI port that will be connected to a HSSI port on another router, you can
also specify clock <clock-source> in your definition.
Then, you must set up a frame relay virtual circuit (VC). The following command line displays a
simplified example of a VC definition:
Setting up a Frame Relay Service Profile
Once you have defined the type and location of your Frame Relay WAN interface(s), you can
configure your XP to more efficiently utilize available bandwidth for Frame Relay
communications.
