## (8) Frame Relay Implementation

### ServiceCenter Router - Frame Relay Configuration

Router(config-if)# encapsulation frame-relay [cisco | ietf] Router(config-if)# frame-relay lmi-type {ansi | cisco | q933i} Router(config-if)# bandwidth kilobits Router(config-if)# frame-relay inverse-arp [protocol ] [dlci]

Note: The other two regional Hub routers will be set up the same way

### Frame Relay Implementation

For the Washington District WAN we have established a 384 Kbps, and our DLCI is OoBiDoobScoobiDoobiBaDoobi. This minimum bandwidth will allow each of the three stations on the WAN to have 128Kbps of bandwith to share amongst it's schools, which should be adequate. In order to implement Frame Relay on the WAN connection to the internet the Data Center must have a router configured for Frame Relay on the appropriate interface as well as a Frame Relay Switch.

### Frame relay benefits

- Frame relay provides a reliable 1.544 Mbps connection
- Virtual circuits connect each site
- Almost no latency, due to it being a single hop
- The router only requires one physical interface to the carrier.

### Management Commands

- Router# show interfaces serial
- Router# show frame-relay pvc
- Router# show frame-relay map
- Router# show frame-relay lmi

### Optional Configuration Commands

- Router(config-if)# keepalive number
- Router(config-if)# frame-relay local-dlci number
- Router(config-if)# frame-relay map protocol protocol-address dlci [broadcast] [ietf | cisco | payload-compress packet-by-packet]

### Subinterface configuration

- Router(config-if)# interface serial number subinterface-number {multipoint | point-to-point}
- Router(config-if)# ip unnumbered
- Router(config-if)# frame-relay interface-dlci dlci-number
