How to configure a Cisco router as a Frame relay switch

Experimental topology

Router (config) #frame-relay switching to simulate a router as a Frame relay switch

Router (config) #inter S1/1

Router (config-if) #clock rate 128000

Router (config-if) #encapsulation Frame-relay Configuration Interface encapsulation and binding relay

The default Frame relay enabled on the interface is encapsulated in the Cisco package and, if connected to a non-Cisco router, use the ITEF parameter

Router (config-if) #no Shu

Router (config) #inter s1/2

Router (config-if) #clo rate 128000

Router (config-if) #encapsulation fr

Router (config-if) #no Shu

Changed state to Upnointer S1/3

Router (config-if) #clo rate 128000

Router (config-if) #encapsulation fr

Router (config-if) #no Shu

Router (config) #inter S1/1

Router (config-if) #frame-relay lmi-type Cisco configuration LMI Type

Router (config-if) #frame-relay intf-type DCE Configuration Interface for Frame Relay DCE

Router (config-if) #inter S1/2

Router (config-if) #frame-relay lmi-type Cisco

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

Router (config-if) #inter S1/3

Router (config-if) #frame-relay lmi-type Cisco

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

Configure the PVC between two interfaces of the router

Router (config) #inter S1/1

Router (config-if) #frame-relay Route Inter s1/2 301

Router (config-if) #frame-relay Route Inter S1/3 401

Router (config-if) #exit

Router (config) #inter s1/2

Router (config-if) #frame-relay Route Inter S1/1 103

Router (config-if) #frame-relay Route 304 Inter S1/3 403

Router (config-if) #exit

Router (config) #inter S1/3

Router (config-if) #frame-relay Route 401 Inter S1/1 104

Router (config-if) #frame-relay Route 403 Inter s1/2 304

Router (config-if) #

Router#show Frame-relay Route

Indicates that the 3 PVC states configured on the router R2 are active

Configuration of R1

Router (config) #inter S1/1

Router (config-if) #ip address 172.16.134.1 255.255.255.0

Router (config-if) #encapsulation FR interface sealing and binding relay

Router (config-if) #frame-relay lmi-type Cisco

Router (config) #inter fa0/0

Router (config-if) #ip add

Router (config-if) #ip address 192.168.1.1 255.255.255.0

Router (config-if) #no Shu

If the Cisco router iOS is version 11.2 and later, the router can automatically negotiate the LMI is the type

So you don't deserve it.

Router (config) #router rip

Router (config-router) #ver 2

Router (config-router) #no auto-summary

Router (config-router) #network 172.16.134.0

Router (config-router) #network 192.168.1.0

Router (Config-router) #exit

R3 and R4 with R1
