Lab 5. Frame Relay Multipoint Subinterface – Static Mapping + Inverse-ARP

Here we’ll try to combine frame relay subinterface with multipoint using Dynamic and Static Mapping. R1 using static mapping & R2 using dynamic mapping.

R1#sh run | sec Serial0/0
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 map ip 12.12.12.2 102 broadcast             --- > static mapping

R2#sh run | Sec Serial0/0
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                                 --- > dynamic mapping

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 map
Serial0/0.1 (up): ip 12.12.12.2 dlci 102(0x66,0x1860), static,
broadcast,
CISCO, status defined, active

Make sure the ping is ok

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:
