e. Issue the undebug all command to turn off debugging on R1.
R1# undebug all
All possible debugging has been turned off
f. Re-apply the frame-relay map ip command to S0/0/0 on R1, but without using the broadcast keyword.
R1(config)# interface s0/0/0
R1(config-if)# frame-relay map ip 10.1.1.2 103
g. Ping R1 from R3. Pings should be successful, but the EIGRP adjacency continues to flap. It may take a
few minutes between each message because of the EIGRP timers.
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
R1(config-if)#

is down: retry limit exceeded
Why does the EIGRP adjacency continue to flap?
____________________________________________________________________________________
Without the broadcast keyword, multicast traffic is not being forwarded over the DLCI specified in the
frame map statement.
h. Replace the Frame Relay map statement and include the broadcast keyword this time.
R1(config-if)# frame-relay map ip 10.1.1.2 103 broadcast
i. Verify that the full routing table is restored and that you have end-to-end connectivity.
R1# show ip route
