R3(config-if)# frame-relay map ip 10.1.1.1 301 broadcast
R3(config-if)# frame-relay map ipv6 2001:db8:acad:b::1 301
R3(config-if)# frame-relay map ipv6 fe80::1 301 broadcast
R3(config-if)# frame-relay map ip 10.1.1.2 301
R3(config-if)# frame-relay map ipv6 2001:db8:acad:b::3 301
R3(config-if)# no shutdown
Why is the no shutdown command used after the no frame-relay inverse-arp command?

If you type the no shutdown command first, Inverse ARP may cause Frame Relay to learn Layer 2 to Layer 3
mappings that you may not want. By turning off the Frame Relay Inverse ARP before issuing the no
shutdown command, you ensure that only the statically mapped connections that you want are part of the
Frame Relay maps.
Step 3: Verify that Frame Relay is active.
a. You should now be able to ping R3 from R1. It may take several seconds after bringing up the interfaces
for the PVCs to become active.
R1# ping 10.1.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/30/40 ms
R1# ping 2001:db8:acad:b::3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:DB8:ACAD:B::3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/28/28 ms
b. Ping R1 from R3.
R3# ping 10.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/28/28 ms
R3# ping 2001:db8:acad:b::1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:DB8:ACAD:B::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 24/26/28 ms
c. Issue the show frame-relay pvc command to display PVC status information on R1 and R3.
R1# show frame-relay pvc
