![]() To configure parameters to control access to the router, perform the following steps. ![]() Sending 5, 100-byte ICMP Echos to 200.200.100.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms Configuring Command-Line Access Router# ping 200.200.100.1 Type escape sequence to abort. ![]() You can lso verify the loopback interface by using the ping command as shown in the following example. Router# show interface loopback 0 Loopback0 is up, line protocol is up Hardware is Loopback Internet address is 200.200.100.1/ bytes, BW 8000000 Kbit, DLY 5000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation LOOPBACK, loopback not set Last input never, output never, output hang never Last clearing of "show interface" counters never Queueing strategy: fifo Output queue 0/0, 0 drops input queue 0/75, 0 drops 5 minute input rate 0 bits/sec, 0 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec 0 packets input, 0 bytes, 0 no buffer Received 0 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 0 packets output, 0 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 0 output buffer failures, 0 output buffers swapped out To verify that you have properly configured the loopback interface, enter the show interface loopback command as shown in the following example. ! interface loopback 0 ip address 200.200.100.1 255.255.255.0 ip nat outside ! interface Virtual-Template1 ip unnumbered loopback0 no ip directed-broadcast ip nat outside ! Verifying the Loopback Interface Configuration The loopback interface points back to virtual-template1, which has a negotiated IP address. This configuration example shows the loopback interface configured on the gigabit ethernet interface with an IP address of 200.200.100.1/24, which acts as a static IP address. The loopback interface in this sample configuration is used to support Network Address Translation (NAT) on the virtual-template interface. Sets the IP address and subnet mask for the loopback interface.Įxits configuration mode for the loopback interface and returns to global configuration mode.Įxample: Configuring the Loopback Interface SUMMARY STEPSĮnters configuration mode for the loopback interface. To configure a loopback interface, follow these steps, beginning in global configuration mode. The loopback interface acts as a placeholder for the static IP address and provides default routing information. Sets the IP address and subnet mask for the specified GE interface.Įnables the GE interface, changing its state from administratively down to administratively up.Įxits configuration mode for the GE interface and returns to global configuration mode. Note GigabitEthernet WAN Interfaces are 0/8 and 0/9 for Cisco C841M-8X ISR and 0/4 to 0/5 for Cisco C841M-4X Router(config)# interface gigabitethernet 0/8Įnters the configuration mode for a Gigabit Ethernet interface on the router. ![]() To configure Gigabit Ethernet (GE) WAN interfaces, follow these steps, beginning in global configuration mode.
