You know the drill. Do the lab, come here to check your answer. This one is on configuring a point-to-point GRE tunnel, using a hostname for the tunnel destination, and with OSPF interface thrown in for some quick review.
This latest lab requires you to configure a point-to-point GRE tunnel, but with no encryption config. Unless this is your first Config Lab, you know the drill. If not: take 5-10 minutes now, read the lab, and type your answer
Creating a PPPoE configuration requires some practice, so do the lab on your own, and check your answers here. More importantly, find a place to do this lab on gear (or VIRL) or a simulator, and spend the time doing
Configuring PPPoE may seem scary, but it is not too hard from a practical sense. The complex part is understanding each command, and the even more complex part is connecting the configuration to the underlying ideas shown in the related
To create a point-to-point GRE tunnel, you just need a few commands. The tricky part is to figure out what parameters to plug into the commands, particularly for the source and destination of each end of the tunnel. Check out
GRE tunnels, without the encryption, can be a breeze to configure and verify – you just need to practice the variations. Today’s post does just that, with a lab topology that looks like two enterprise routers connected to the Internet,
The new ICND2 book takes extra care to map out the configuration required for PPPoE, along with the somewhat complex verification and troubleshooting details as well. This lab is meant to be straightforward so that you get practice on getting
PPP over Ethernet (PPPoE) can be one of the more challenging configuration topics on the CCNA exam. Why? First, many network engineers ignore PPPoE as something that is configured only occasionally. Then, when faced with configuring it, you can follow
Configuring a static GRE tunnel, before adding the IPsec encryption, takes just a few commands. Have you mastered those commands yet? If not, check out the lab exercise first, and then come back here for the answer and some comments.
#GRE – that is, Generic Route Encapsulation – gives us a way to encapsulate IP packets inside another IP packet. Why? Often times, the reason is to create an Internet VPN, forwarding encrypted IP packets inside IP packets that can
