Create loopback cable how to#
You need the following equipment to create the loopback: A 6-inch long CAT5 cable An RJ-45 connector A crimping tool Figure 1 illustrates how to create a loopback plug for an RJ-45 Ethernet interface. Success rate is 100 percent (5/5), round-trip min/avg/max = 0/16/40 ms R1#ping 4.0.0.1 Action To create a loopback plug, cross pin 1 (TX+) and pin 3 (RX+) together, and cross pin 2 (TX-) and pin 6 (RX-) together. Sending 5, 100-byte ICMP Echos to 3.0.0.1, timeout is 2 seconds: Sending 5, 100-byte ICMP Echos to 2.0.0.1, timeout is 2 seconds: via 1.0.0.1, 00:00:26, FastEthernet0/0ħ.0.0.0/8 directly connected, Loopback3 Now check every interfaces including loopback interfaces by pinging ip assigned on each loopback interfaces: R1#ping 2.0.0.1 R2# See RIP Databases on Router R2: R2#show ip rip database Let’s check Router R2 interfaces ip addresses: R2#show ip interface briefĬonfigure Routing RIP on Router R2: R2#config terminal R1# Configure IP ADDRESS on INTERFACES OF ROUTER R2: Router>enable

Here I am going to assign ip address on router real interfaces and also going to create virtual interfaces and loopback interfaces and assign ip address on loopback interfaces.
