DECbrouter 90 frame relay configuration examples This is an example of configuring BRUT V10.06 using the Frame-Relay switching feature with two BRUT connected to it's serial ports utilizing Frame-Relay subinterfaces. ------------------ | | | BRUTN | | ----------- | | | | | | S0 S1 | ------------------ DCE | | DCE DLCI #101 | | DLCI #100 | | / \ / \ / \ / \ DTE / \ DTE --------- --------- | S0 | | S0 | | BRUTK | | BRUTJ | --------- --------- BRUTN#show config version 10.0 ! no ip routing frame-relay switching ! interface Ethernet0 no ip address no mop enabled ! interface Serial0 no ip address encapsulation frame-relay ! ! set the encapsulation to Frame-Relay ! keepalive 15 ! !

This command allows the BRUT to treat Frame-Relay as a WAN. This is a ! point-to-point circuit, you can configure multiple subinterfaces on one ! interface. With subinterfaces configured as point-to-point circuits, there is ! no need for frame-relay maps or frame-relay Inverse arp. ! ! ip address 17.1.1.253 255.255.255.0 ! ! Give the subinterface the IP address and not the interface. This allows you ! to have multiple subinterfaces on the same interface in different IP subnets. ! frame-relay interface-dlci 101 ! ! This command defines the DLCI which this subinterface will use. There can be ! only one DLCI per subinterface. However, since you can have multiple ! subinterfaces per interface, you can still have multiple DLCIs per interface. ! router rip network 17.0.0.0 network 16.0.0.0 ! end BRUTJ#show config version 10.0 ! interface Ethernet0 ip address 18.1.1.254 255.255.255.0 no mop enabled ! interface Serial0 no ip address encapsulation frame-relay ! ! set the encapsulation to Frame-Relay ! keepalive 15 ! !
