3Com 10014299 Configure local virtual circuit, Relay FRF.16, Interconnect LANs via Private Line

RouterA and RouterB are directly connected via the serial ports Serial 0 and Serial1 and through Frame Relay protocol. The two serial ports are bundled together to provide wider bandwidth.

Interconnect LANs via Private Line

Typical Frame Relay Configuration Example 277

[Router-Serial1]ip address 202.38.163.253 255.255.255.0

bConfigure the link layer protocol of the interface to Frame Relay

[Router-Serial1]link-protocol fr

[Router-Serial1]fr interface-type dte

cConfigure static address mapping

[Router-Serial1]fr map ip 202.38.163.251 dlci 80

I. Networking Requirement

Two Routers are directly connected via a serial port. Router A works in the Frame Relay DCE mode, and Router B works in the Frame Relay DTE mode. The router use dynamic address mapping.

bConfigure the link layer protocol of the interface to Frame Relay

[Router-Serial1]link-protocol fr

[Router-Serial1]fr interface-type dce

cConfigure local virtual circuit

[Router-Serial1]fr dlci 100

2Configure Router B:

aConfigure interface IP address

[Router]interface serial 1

[Router-Serial1]ip address 202.38.163.252 255.255.255.0

bConfigure the link layer protocol of the interface to Frame Relay

[Router-Serial1]link-protocol fr

[Router-Serial1]fr interface-type dte
