Dear Mr Junos, I am Dheerendra from India... As per your query regarding loopback interfaces.I have found some suitable info for your loopback interfaces. The answer to your question 1 is that you can create more than 2 loopback interfaces.Infact the the total number of loopback interfaces that can be created is from 0-0-2147483647 The answer to your question 2 is how to create loopback interfaces is as follows: 1.login to the reqd router 2.enter into the enable mode 3.type the following command The following will give you the exact idea of what exactly do you mean by loopback interface: You can specify a software-only interface called a loopback interface to emulate an interface. It is supported on all platforms. A loopback interface is a virtual interface that is always up and allows Border Gateway Protocol (BGP) and remote source-route bridging (RSRB) sessions to stay up even if the outbound interface is down. You can use the loopback interface as the termination address for BGP sessions, for RSRB connections, or to establish a Telnet session from the device's console to its auxiliary port when all other interfaces are down. You can also use a loopback interface to configure IPX-PPP on asynchronous interfaces. To do so, you must associate an asynchronous interface with a loopback interface configured to run IPX. In applications where other routers or access servers attempt to reach this loopback interface, you should configure a routing protocol to distribute the subnet assigned to the loopback address. Packets routed to the loopback interface are rerouted back to the router or access server and processed locally. IP packets routed out the loopback interface but not destined to the loopback interface are dropped. This means that the loopback interface serves as the Null 0 interface also.
