Frame Relay Configuration

Frame Relay network in China is a public transport network (such as the Chinese telecom is to provide Frame Relay network services), mainly for the transfer of data service, the user router as DCE connected to the Frame Relay switch as DCE, through the Frame Relay network to establish virtual circuit, virtual circuit with data Link identification code to identify

Frame Relay Configuration steps

( 1 ) as DTE the router configuration

① Specifies the router interface or sub-interface, and configures the Network layer protocol address.

② specifying the Frame Relay protocol and its encapsulation Format (required)

R1 (config-if) # encapsulation Frame-relay Cisco |IETF// on the same side as Cisco , otherwise select IETF

③ Setting the bandwidth (optional)

④ Settings LMI type (optional)

⑤ indicates that the point-to sub-interface is connected DLCI .

⑥ configuring dynamic or Static address mapping (required)

⑦ Configuration SVC (optional)

( 2 ) as DCE the Frame Relay switch configuration

Example of Frame Relay configuration

Example 8-2 the router emulates the configuration of the frame relay switch, connecting the network, requiring R1 and the R2 enabled EIGRP Routing Protocol

R1 Configuration

R1 (config) #int Lo0//loopback0 for testing, because even the computer is too memory-intensive, I used GNS3 to do the experiment

R1 (config-if) #ip add 192.168.10.1 255.255.255.0

R1 (config-if) #router EIGRP 1

R1 (config-router) #network 192.168.10.0

R1 (config-router) #network 10.1.1.0

R1 (Config-router) #exit

R1 (config) #int s0/0

R1 (config-if) #ip add 10.1.1.1 255.255.255.252

R1 (config-if) #encapsulation Frame-relay

R1 (config-if) #shut   // Before you configure the Frame relay switch, you can first turn off the router WAN port

R 2 Configuration

R2 (config) #int Lo0

R2 (config-if) #ip add 192.168.20.1 255.255.255.0

R2 (config-if) #router EIGRP 1

R2 (config-router) #network 192.168.20.0

R2 (config-router) #network 10.1.1.0

R2 (Config-router) #exit

R2 (config) #int s0/0

R2 (config-if) #ip add 10.1.1.2 255.255.255.252

R 2 (config-if) #encapsulation Frame-relay

R 2 (config-if) #shut  // Before you configure the Frame relay switch, you can first turn off the router WAN port

Frswitch Configuration

① in R1 and the R2 created between PVC :

Frswitch (config) # Frame-relay Switching    // enables frame Relay switching in global mode, enabling it to DLCI rather than based on IP Address Forwarding frame

Frswitch (config) #int s0/0

Frswitch (config-if) #clockrate 64000

Frswitch (config-if) #encapsulation Frame-relay        // ② Changing the interface closure type to Frame Relay

Frswitch (config-if) #frame-relay intf-type DCE// interface is changed to DCE

Create PVC

Frswitch (config-if) #frame-relay Route102int s 0/1201//will beDLCI 102from the interfaces0/0of incoming traffic through InterfaceS0/1forwarded toDLCI201

Frswitch (config-if) #noshut

Frswitch (config) #ints0/1

Frswitch (config-if) #clockrate 64000

Frswitch (config-if) #encapsulation Frame-relay

Frswitch (config-if) #frame-relay intf-type DCE

Frswitch (config-if) #frame-relay Route 201 int S 0/0 102

Frswitch (config-if) #no shut
