Lab 6. Frame Relay Point-to-Point Subinterface

Now let's make frame relay point-to-pont using subinterface

R1(config)#int s0/0
R1(config-if)#no shu
*Mar 1 00:00:56.919: %LINK-3-UPDOWN: Interface Serial0/0, changed state to up
*Mar 1 00:00:57.927: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to up
R1(config-if)#encap frame-relay
R1(config-if)#int s0/0.1 point-to-point
R1(config-subif)#ip add 12.12.12.1 255.255.255.0
R1(config-subif)#fram inte 102
R1(config-fr-dlci)#
*Mar 1 00:01:43.251: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to down
*Mar 1 00:02:03.251: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to up

R2(config)#int s0/0
R2(config-if)#no shu
*Mar 1 00:02:23.383: %LINK-3-UPDOWN: Interface Serial0/0, changed state to upn
*Mar 1 00:02:24.391: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to up
R2(config-if)#encap fram
R2(config-if)#int s0/0.1 point-to-point
R2(config-subif)#ip add 12.12.12.2 255.255.255.0
R2(config-subif)#fram int 201
R2(config-fr-dlci)#
*Mar 1 00:03:07.719: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to down
*Mar 1 00:03:27.719: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to up

Let's check the map, pvc, and ping

R1(config-fr-dlci)#do sh fram map
Serial0/0.1 (up): point-to-point dlci, dlci 102(0x66,0x1860), broadcast
status defined, active

R2(config-fr-dlci)#do sh fram map
Serial0/0.1 (up): point-to-point dlci, dlci 201(0xC9,0x3090), broadcast
status defined, active

R2(config-fr-dlci)#do ping 12.12.12.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 12.12.12.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/17/44 ms
