Point to point frame relay

Scenario- The is scenario is that we have two different sites on different locations and we have to establish an point- point connection between them with the help of  

 

               Frame relay switching method , here as u can see in given image we have to Routers name Site1 and site2 (that Both of DTE (Data terminal Equipment) and we hav another router name FRS ( Frame relay switch) which creates link between both of the sites and that also callrd DCE (Data communication equipment) , here we going to create to point to point link which goes through FRS , for identify both link we taken two DLCI (Data link connection identifier) no. and assigning two different subnet for both of the links that is 192.168.110.0/30  with DLCI-100 and 192.168.120.0/30 with DLCI-200.

 FRS configurations

(config)#frame-relay switching
(config)#interface s0/0
(config-if)#encapsulation frame-relay
(config-if)#frame-relay intf-type dce
(config-if)#frame-relay route 100 interface serial 0/1 100
(config-if)#frame-relay route 200 interface serial 0/1 200
(config-if)#exit
(config)#interface s0/1

(config-if)#encapsulation frame-relay

(config-if)#frame-relay intf-type dce
(config-if)#frame-relay route 100 interface serial 0/0 100
(config-if)#frame-relay route 200 interface serial 0/0 200

Site 1 Configuration

(config)#interface s0/0
(config-if)#encapsulation frame-relay
(Config-if)#no ip adderess
(config-if)#exit
(config)#interface s0/0.100 point-to-point
(config-subif)#ip add 192.168.110.1 255.255.255.252
(config-subif)#frame-ralay interface-dlci 100
(config-subif)#exit
(config)#interface s0/0.200 point-to-point
(config-subif)#ip add 192.168.120.1 255.255.255.252
(config-subif)#frame-ralay interface-dlci 200

Site 2 Configuration

(config)#interface s0/0
(config-if)#encapsulation frame-relay
(Config-if)#no ip adderess
(config-if)#exit
(config)#interface s0/0.100 point-to-point
(config-subif)#ip add 192.168.110.2 255.255.255.252
(config-subif)#frame-ralay interface-dlci 100
(config-subif)#exit
(config)#interface s0/0.200 point-to-point
(config-subif)#ip add 192.168.120.2 255.255.255.252
(config-subif)#frame-ralay interface-dlci 200

=================================================================
Now if you want to identify , links are activated or working fine put the command  :-
#show frame-relay pvc
You see are two links which hasbeen acivated or you can indentify with pinging of each other like

From Site1 Router,
 #ping 192.168.110.2 or #ping 192.168.120.2

It will show you that links are giving proper responce to each other.


Thank for reading......... See you soon
