Although NTP allows us to use any interface for NTP Server reference, but we should always use loopback interface for this purpose. A physical interface can be down due to several reasons, but loopback interface once up, remains up until we manually shut it down. Let’s create a loopback...
Let’s use this topology to configure RIPNG. I’m going to create a loopback interface on each router to advertise in RIPNG. Note that I don’t have any global unicast IPv6 addresses on the FastEthernet interface because the RIPNG updates will be sent using the link-local addresses. R1...
This will take more disecting but you will find the info you are looking for this way too. show interface sh int -This will give more detailed information about all interfaces on the router. You will need to disect the output to find the info you need here as well. For the quick snap...
An IP address has to be assigned to the loopback interface now. Go to Start -> Control Panel -> Network and Internet -> Network Sharing Center, from the left pane click “Network Connections”, right-click your internet connection (it can be a WLAN connection, dialup connection, PPPoE co...

cross-over plug and set the clocking to internal. You can use loopback commands to do it as well but I prefer external plug which is a more complete test IMHO (traffic leaves the interface and comes back). Set encaps to HDLC.
In Cisco IOS, typing a new IP address on an interface will simply replace the old address. In a few weeks time we’ll go into more detail on this, when I make a post all about interfaces in Junos. The second way to correct mistakes is to delete the incorrect config. In the same ...
ll see network 192.168.12.0 /24 and a default route as inter-area (LSA Type 3). Because area 1 is a stub area, we won’t see 1.1.1.0/24 as external type 2 (LSA type 5). First, we’ll create a loopback interface on R3 and redistribute it into OSPF to show you the NSSA area...
Cisco can do this if it wanted to. On Cisco switches & IOS, re-entering the interface name or up arrow until it shows is the way to go for good measure. Shutting down the interface to see which interface it is could be a bit of a radical measure Brocade VDX switches, which run ...
