Configuring a Switched PVC between Extended Addressing and Non-Extended Addressing
Interfaces
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.
existing routes to disappear from the interface.

The DLCI value with Extended Addressing is
between 16 and 8388607.
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.
