INTEGRATED BRIDGING AND ROUTING OVER FRAME-RELAY

Here I show you how to configure bridging over Frame-Relay

Frame-Relay network is simulated using Back-to-Back connection
For Back-to-Back frame-relay connection to work, same DLCI number to be used on both ends of the connection

 Topology

R1 s1/0  <-- B2B Connection --> R2 s1/0

R1:

bridge irb

bridge 1 protocol ieee

bridge 1 route ip

interface BVI1

 ip address 10.8.14.1 255.255.255.0

interface Serial1/0

 no ip address

 encapsulation frame-relay

 frame-relay map bridge 104 broadcast CISCO

 frame-relay interface-dlci 104

 bridge-group 1

R2:

bridge irb

bridge 1 protocol ieee

bridge 1 route ip

interface BVI1

 ip address 10.8.14.4 255.255.255.0

frame-relay switching

interface Serial1/0

 no ip address

 encapsulation frame-relay

 clock rate 128000

 frame-relay map bridge 104 broadcast CISCO

 frame-relay interface-dlci 104

 frame-relay intf-type dce

 bridge-group 1

RESULT

R2#ping 10.8.14.1  

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.8.14.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 12/13/14 ms

R1#ping 10.8.14.4    

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.8.14.4, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 10/12/14 ms

R1#sh frame-relay map
