I have been working in enterprise networking for ~5 years now. I'm in the military and finally decided to try acquiring my CCNA here soon. I have been able to do every single lab leading up to this point without assistance. This one was quite difficult, but I was able to configure both sides by only googling the GRE tunnel creation commands for assistance. A neat trick you can use to track whether your tunnel is working is to run a continuous ping using "ping -t" or "ping -n x" from one of the office PCs pinging the other office PC. Then, issue a "show interface tunnel x" and if you spam that show command repeatedly as the continuous ping runs, you'll notice the packet input counter going up if the traffic is properly being tunneled using GRE. Great lab Jeremy!

Edit: Another cool method I forgot about is running a traceroute on the office PCs to one another. You'll notice the ISP hops aren't included in the traceroute and instead it's replaced with the tunnel IP as the intermediary hop.

Hi Jeremy, nice video. It would be beneficial to mention that the source/destination tunnel addresses must be routable addresses! I've seen some misleading videos where a loopback interface is being used with a private IP address, of course this will work in a lab if the network's are added to the routing processes however in the real world it won't. The addresses must be public, the tunnel interface however is private. Shame you didn't show the recursive routing problems that can arise with OSPF over GRE. Thanks again...

Thank you, Mr. Jeremy, for your help and support. I have a question in this lab regarding the ping between PC1 and PC2. Why did the ping fail before configuring OSPF even though there was a static route already configured on both routers? Thank you 😊

@JeremysITLab Жыл бұрын

Hi Salah! Thanks for being a channel member :) The pings fail because the ISP routers don't have routes to the customer's internal networks. The default route on R1 uses the ISP router as the next hop, so the packets are not tunneled over the GRE tunnel. They are sent directly to the ISP. When the routers use OSPF to share routes, R1 learns that it can reach R1's LAN via the GRE tunnel, so it will send the packets via the GRE tunnel. *The packets R1 sends are still destined for 10.0.2.100, which the ISP routers don't have a route to. However, using the tunnel those packets are encapsulated with a GRE header + an additional IP header, and that IP header's destination IP is 200.0.0.2, which the ISP routers do have a route to.

@Alien-Networking Жыл бұрын

@Jeremy's IT Lab Thank you so much Mr. Jeremy for clarification 😊

@kenlynn8857 Жыл бұрын

I was curious about the default route to SP1/2 so I "played" by changing them to 0.0.0.0 0.0.0.0 192.168.1/2. The Tunnel still came up and I believe the tunnel created a static route through 100.... and 200.... I took out the "default -192" routes I created and everything appeared to work, (one step ahead of yours). It appears that we both had a problem creating the tunnel without at least one set of the routes, but once established, it appears nether are required. Question: If you leave a default route through the ISP (100...), do you alter traffic (same path/different name) that should follow the 192... OSPF routing through the tunnel?

Hi, you have used all wildcard mask bits as 0.0.0.0 when configuring the OSPF network command. For example, at 08:08, network 192.168.1.1, wildcard mask should be 0.0.0.3 for /30 but you used 0.0.0.0 instead. Please explain
