This lab asks you to do a basic migration: move from using two parallel serial links as independent links to instead treating them as one layer 3 link using MLPPP. This lab requires new configuration as well as analysis of
Part 3 - Wide Area Networks
Multilink PPP (MLPPP) makes multiple parallel links act like one link from a layer 3 perspective. In this next lab, the lab begins with a working configuration that does not use MLPPP, with two parallel serial links between two routers.
Configuring multilink PPP (MLPPP) uses a large number of commands for a single feature. However, many of the commands are repetitive on several interfaces. The trick is to figure out which commands are repeated on both the physical and multilink
Multilink PPP (MLPPP) makes multiple parallel links act like one link from a layer 3 perspective. Then, when a router’s layer 3 routing decides to forward a layer 3 packet out the layer 3 MLPPP multilink interface, the router has
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,
