Hello everybody!

Could somebody tell me how to configure frame relay between R2 and R6 (BlockB)? I've been trying and for some reason i could not do it.

this is what i did (this is from a lab that i have)

s0/0
R2(interface)#ip add 172.16.13.1 255.255.255.248
#bandwidth 64
#no shut
#encapsulation frame-relay
#no frame-relay inverse-arp
#frame-relay map ip 172.16.13.3 406 broadcast
#frame-relay map ip 172.16.13.1 406

s0/0
R6(interface)#ip add 172.16.13.3 255.255.255.248
#bandwidth 64
#no shut
#encapsulation frame-relay
#no frame-relay inverse-arp
#frame-relay map ip 172.16.13.1 604 broadcast
#frame-relay map ip 172.16.13.3 604

and it did not work

and I also notice that in the lab_topology_serial picture R2 and R6 are showing s0/0 and s0/1 but when i am in console the 2 interfaces are s0/0/0 and s0/0/1, any reason why the picture is showing one thing and in the console another?

thanks

Between R2 and R6 you need to reference DLCIs 206 and 602, respectively.

However, R6's s0/0/0 is not working at the moment. The line protocol is down! It can send, but not receive, LMI. The issue could be on the FR switching not having clock rate and/or frame-relay intf-type dce.

R6(config-line)#do s int s0/0/0
Serial0/0/0 is up, line protocol is down
  Hardware is GT96K Serial
  Internet address is 172.16.13.3/29
  MTU 1500 bytes, BW 1544 Kbit/sec, DLY 20000 usec,
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation FRAME-RELAY, loopback not set
  Keepalive set (10 sec)
  CRC checking enabled
  LMI enq sent  4695, LMI stat recvd 0, LMI upd recvd 0, DTE LMI down
  LMI enq recvd 0, LMI stat sent  0, LMI upd sent  0
  LMI DLCI 1023  LMI type is CISCO  frame relay DTE

Update: I failed to look at the LAB setup to see that there is a frame-relay switch. The previous post will likely put you on the correct path.

However, I'll leave piece of information below as I did encounter this on a Cisco Netacad skills final.

If you are doing back to back frame relay without a frame relay switch you need to configure 'no keepalives' on both interfaces to disable LMI.
