interface Loopback0
description Primary
interface for connecting to this router
ip address 10.0.75.4
255.255.255.255
| The following interface definition for Loopback1 is being used to simulate the presence of an entire class B ip network. This loopback interface provides a way to get 172.17.0.0 into the lab's routing table. The presence or not of this network in the lab's routing table will be used as part of the excercise to demonstrate a routing loop. |
| The following two lines provide a default destination for this router to deliver packets destined for networks which it has no entry in its routing table. There are two entries because this router has twodifferent links it can use to forward packets on through. The entry with the number 200 at the end of it is normally placed into the routing table as the gateway of last resort, *unless* the link on this router which is numbered with the 10.0.140.0 network is down. In that case, the entry with the 210 at the end of it is placed in the routing table. 200 and 210 are routing metrics which allow the person configuring the router to tell the router how to prioritize static route entries to the same destination. The lower the metric number, the *higher* in order of precedence that router gives to the entry. The default metric for a static route is 0, normally giving it priority over any other entry to the same destination. In this case, the static route with the metric of 200 directs packets over the true 1.544Mbps T1 link. The static route with the 210 metric directs traffic over the other link that only runs at 64Kbps. |
