The following example shows how to create a serial interface on a SPA with Frame Relay encapsulation
and a serial subinterface with a PVC on router 2, which is connected to router 1:
RP/0/0RP0RSP0/CPU0:router# configure
RP/0/0RP0RSP0/CPU0:router(config)# interface serial 0/1/0/1
RP/0/0RP0RSP0/CPU0:router(config-if)# encapsulation frame-relay
RP/0/0RP0RSP0/CPU0:router(config-if)# no shutdown
RP/0/0RP0RSP0/CPU0:router(config-if)# end
