Command IP NAT Enable Use This command is used to enable NAT on an interface. This command figures out whether the interface is inside or outside based on the source IP addresses of packets. IP NAT enable can not translate local router traffic. Syntax Router(config-if)#ip bandwidth-percent eigrp <AS> …
Command Frame-Relay Inverse-Arp Use This command enables frame-relay inverse-arp. Frame-relay uses inverse-map to dynamically learn remote IP addresses and its local DLCIs. Syntax Router(config-if)#frame-relay inverse-arp OR Router(config-if)#frame-relay inverse-arp ip <dlci> Example In this example we will configure R4 to use frame-relay. CopyR4(config)#int s0/0 R4(config-if)#encapsulation frame-relay R4(config-if)#ip add 10.4.4.4 255.255.255.0 …
