Lab 3. Frame Relay Multipoint Subinterface: Inverse-ARP

Before we already did frame-relay using interface and now we’ll try to do frame-relay using subinterface.




After activate frame-relay in interface, we create subinterface using multipoint. To do dynamic mapping just type ‘frame-relay interface-dlci 102’ in R1.

R1#sh run | beg Serial
interface Serial0/0
no ip address
encapsulation frame-relay
clock rate 2000000
!
interface Serial0/0.1 multipoint
ip address 12.12.12.1 255.255.255.0
snmp trap link-status
frame-relay interface-dlci 102
!

R2#sh run | beg Serial
interface Serial0/0
no ip address
encapsulation frame-relay
clock rate 2000000
!
interface Serial0/0.1 multipoint
ip address 12.12.12.2 255.255.255.0
snmp trap link-status
frame-relay interface-dlci 201
!

Let’s check the mapping and ping

R1#sh fram map
Serial0/0.1 (up): ip 12.12.12.2 dlci 102(0x66,0x1860), dynamic,
broadcast,, status defined, active

R2#sh fram map
Serial0/0.1 (up): ip 12.12.12.1 dlci 201(0xC9,0x3090), dynamic,
broadcast,, status defined, active

R1#sh fram pvc
PVC Statistics for interface Serial0/0 (Frame Relay DTE)
Active Inactive Deleted Static

Switched 0 0 0 0
Unused 0 0 0 0
DLCI = 102, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0/0.1

R1#ping 12.12.12.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 12.12.12.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/20/56 ms
