![]() ![]() The following example shows valid IP address configurations on two loopback interfaces. Up to thirty-two IP addresses are supported on a loopback interface. You can configure multiple IP addresses on a loopback interface ( lo0 to lo7). The ping command is used to verify the internal IP configuration on a local host. In the same way, if you configure a loopback interface ( lo1) with IP address 172.16.101.8, you cannot configure another loopback interface ( lo2) with IP address 172.16.101.8. ![]() This means that the address cannot be used by a VLAN interface or another loopback interface.įor example, if you configure a VLAN with IP address 172.16.100.8/24, you cannot configure a loopback interface with IP address 172.16.100.8. The maximum number of IP addresses supported on a switch is 2048, which includes all IP addresses configured for both VLANs and loopback interfaces (except for the default loopback IP address 127.0.0.1).Įach IP address that you configure on a loopback interface must be unique in the switch. I have seen the lab for CCNP ROUTE exam it stataes that you must aable to ping and telnet from loopback interface 101 on R1 to ip address like 172.1.1. Loopback interfaces share the same IP address space with VLAN configurations. ![]() You can configure a loopback interface only from the CLI you cannot configure a loopback interface from the WebAgent or Menu interface. At the command line, type these commands: For IPv4: PING 127.0.0. ![]()
