Router R3 Configuration


R3(config)#int f 0/0 (Configure VLAN1 and VLAN number)

R3(config)#int f 0/0.1

R3(config-subif)#encapsulation dot1q 1 native

R3(config-subif)#ip address <ip addr> <subnet mask>


R3(config)#int f 0/0.2

R3(config-subif)#encapsulation dot1q <vlan number>

R3(config-subif)#ip address <ip addr> <subnet mask>


R3(config)#int s0/0

R3(config-if)#encapsulation frame-relay [ cisco | ietf ]

R3(config-if)#ip address <ip addr> <subnet mask> (if not using subinterface)

R3(config-if)#bandwidth <bandwidth > (in K, eg 64 to change from default. Eg serial - 1544K, Eth 10M, Fa 100M)

R3(config-if)#frame-relay lmi-type [ cisco | ansi | q933a ]

R3(config-if)#frame-relay map ip <ip addr> <dlci number> [ broadcast ]


If using subinterface (eg 103 to match with hyperthetical dlci 103)

R3(config-if)#int s0/1.103 point-to-point

R3(config-subif)#ip address <ip addr> <subnet mask>

R3(config-subif)#frame-relay interface-dlci 103


R3(config)#Router RIP

R3(config-router)#network <ip addr> (IP of R1 network)

R3(config-router)#network <ip addr> (IP of R2 network)


R3(config)ip route <ip addr> (IP of next hop to outside world, eg R12)

Frame Relay Displays

show frame-relay lmi (Displays LMI statistics)

show frame-relay pvc (Displays status of all the PVCs and DLCIs)

show frame-relay map (Displays current map entries and information about them, eg DLCI, IP of remote, PVC status)

show running-config (Shows DLCIs under each interface and all configured PVCs)

show interface (Displays information about the DLCI and the LMI, and the encapsulation Layer 1 & 2 status)


debug frame-relay lmi (Shows packets in/out and status messages)
