Frame-Relay Switching

Brief

Configuring R3 as Frame-relay switch for connecting R1 to R2 using PVC 132 and 231

Network Diagram:

 

R3 Configuration:

Frame-relay switching ! interface Serial1/2  encapsulation frame-relay  serial restart-delay 0  clock rate 64000  frame-relay intf-type dce ! interface Serial1/3  encapsulation frame-relay  serial restart-delay 0  clock rate 64000  frame-relay intf-type dce ! connect R1_R2 Serial1/2 132 Serial1/3 231

R2 Configuration:

interface Serial1/1  ip address 155.1.12.2 255.255.255.0  encapsulation frame-relay  no frame-relay inverse-arp  no shutdown

R1 Configuration:

interface Serial1/1  ip address 155.1.12.1 255.255.255.0  encapsulation frame-relay  no shutdown

Verification

R3:

R3#sh frame-relay pvc | in SWI DLCI = 132, DLCI USAGE = SWITCHED, PVC STATUS = ACTIVE, INTERFACE = Serial1/2 DLCI = 231, DLCI USAGE = SWITCHED, PVC STATUS = ACTIVE, INTERFACE = Serial1/3 R3#sh connection all ID   Name            Segment 1              Segment 2                  State    ================================================================================ 1    R1_R2           Se1/2 132              Se1/3 231                  UP

R2:

Rack1R2#sh frame-relay map Serial1/0 (up): bridge dlci 205(0xCD,0x30D0), static,               broadcast,               CISCO, status defined, active Serial1/1 (up): ip 155.1.12.1 dlci 231(0xE7,0x3870), dynamic,               broadcast,, status defined, active

R1:

R1#ping 155.1.12.2 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 155.1.12.2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 20/20/20 ms
