I do not see any infromation about encapsulation in show frame-relay map…

there are two reasons why C is the answer:

1) none of the other commands are valid
2) the LMI type is NOT encapsulation

1841-bott#sh inter serial 0/0/0
Serial0/0/0 is up, line protocol is up
Hardware is GT96K Serial
Internet address is 192.168.2.1/24
MTU 1500 bytes, BW 1544 Kbit/sec, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation FRAME-RELAY IETF, loopback not set
Keepalive set (10 sec)
CRC checking enabled
LMI enq sent 227, LMI stat recvd 227, LMI upd recvd 0, DTE LMI up
LMI enq recvd 0, LMI stat sent 0, LMI upd sent 0
LMI DLCI 1023 LMI type is CISCO frame relay DTE

From packet-tracer:

WEST#show frame map
Serial0/0/0 (up): ip 10.0.0.1 dlci 201, static, broadcast, CISCO, status defined, active
Serial0/0/0 (up): ip 10.0.0.3 dlci 203, static, broadcast, CISCO, status defined, active
Serial0/0/0 (up): ip 10.0.0.4 dlci 204, static, broadcast, IETF, status defined, active

Command show frame-relay lmi shows only LMI type (CISCO, ANSI, Q933a), not encapsulation type (CISCO, IETF)

be that as it may, the command in answer A is not show frame-relay map. show inter serial is a valid command which gives the correct answer

sir can you explain difference between point to point or multipoint configuration of frame relay protocol

sc

1) correct is “sh frame-relay map”
RouterA#show frame-relay map
Serial0 (up): ip 157.147.3.65 dlci 980(0x3D4,0xF440), dynamic,
broadcast,, status defined, active

#show frame-relay map
Serial0/0/0 (up): ip 10.1.1.2 dlci 102 (0x66, 0x1860), static, broadcast, CISCO, status defined, active

2)# sh interfaces Serial
% Incomplete command.

you need to write to check interface options

A is correct

I think if all of you go back you can find out with either A or C.
I looked up CISCO commands and it says map, but looking up interface I found it as well.

Amazing blog! Do you have any recommendations for aspiring writers?
I’m hoping to start my own site soon but I’m a little lost on everything.
Would you recommend starting with a free platform like WordPress or go for a paid option? There
are so many options out there that I’m completely confused ..
Any suggestions? Thanks!
