Configuring Frame Relay to ATM Virtual Connections
Note Soft PVC route optimization should not be configured with constant bit rate (CBR) connections.
Configuring a Frame Relay Interface with Route Optimization
Soft PVC route optimization must be enabled and configured to determine the point at which a better
route is found and the old route is reconfigured.
To enable and configure a Frame Relay interface with route optimization, perform the following steps,
beginning in global configuration mode:
Example
The following example shows how to configure an interface with a route optimization interval
configured as every 30 minutes between the hours of 6:00 P.M. and 5:00 A.M.:
Switch(config)# atm route-optimization percentage-threshold 45
Switch(config)# interface serial 1/0/0:1
Switch(config-if)# atm route-optimization soft-connection interval 30 time-of-day 18:00 5:00
Displaying a Frame Relay Interface Route Optimization Configuration
To display the Frame Relay interface route optimization configuration, use the following privileged
EXEC commands:
Example
The following example shows the route optimization configuration of serial interface 1/0/0:1:
Switch# show running-config
Building configuration...
<information deleted>
Command Purpose
Step1 Switch(config)# atm route-optimization
percentage-threshold value
Configures the ATM route optimization
threshold.
Step2 Switch(config)# interface serial
card/subcard/port:cgn
Switch(config-if)#
Selects the interface to configure. Enter the
interface number of the source end of the soft
PVC. Route optimization works for the source
end of a soft PVC only and is ignored if
configured on the destination interface.
Step3 Switch(config-if)# atm route-optimization
soft-connection [interval minutes] [time-of-day
{anytime | start-time end-time}]
Configures the interface for route optimization.
Command Purpose
show running-config Shows the serial interface configuration route
optimization configuration.
show interfaces [serial
card/subcard/port:cgn]
Shows the serial interface configuration.
