Cisco IOS Release 12.0(17)S
Configuring a Switched PVC between Extended Addressing and Non-Extended Addressing 
Interfaces
A PVC can also be configured for switching between an extended address and a non-extended address. 
Note
The DLCI values for the two interfaces in a switched PVC can be different. See 
 for additional information on the use of DLCI values.
A sample configuration is show in this section:
 provides the commands to configure a switched PVC for the first interface with standard 
Frame Relay DLCI values. 
 provides the commands to configure the second interface with Frame Relay Extended 
Addressing on the PVC (extended DLCI values).
Table 3
Configure the First Interface with Standard DLCI Values
Table 4
Configure the Second Interface with Extended Addressing
Note
Changing a previously configured interface between standard and extended addressing will cause all 
existing routes to disappear from the interface. 
Command
Purpose
Step 1
Router(config)# frame-relay switching
Enables Frame Relay switching.
Step 2
Router(config)# interface interface[slot/port]
Specifies interface for configuration mode.
Step 3
Router(config-if)# encapsulation frame-relay
Turns on standard frame-relay encapsulation for 
the specified interface.
Step 4
Router(config-if)#  frame-relay intf-type dce
Specifies the interface type.
Step 5
Router(config-if)# frame-relay route dlci interface 
interface[slot/portdlci
Adds PVC from one slot/port to another slot/port. 
The DLCI value for a standard (non-extended) 
interface is between 16 and 1007.
Step 6
Router(config-if)# exit
Exits from PVC configured interface.
Command
Purpose
Step 1
Router(config)# interface interface[slot/port]
Specifies interface for configuration mode for 
second slot/port PVC configuration.
Step 2
Router(config-if)# encapsulation frame-relay extended
Turns on Extended Addressing encapsulation for 
the specified interface. 
Step 3
Router(config-if)# frame-relay nni-annex1
Turns on annex1 event driven feature for second 
slot/port configuration.
Step 4
Router(config-if)# frame-relay route dlci interface 
interface[slot/portdlci
Adds PVC from second slot/port to first slot/port. 
The DLCI value with Extended Addressing is 
between 16 and 8388607.
Step 5
Router(config-if)# end
PVCs have now been added to both slot/ports.
