I hope you're enjoying the labs! If you want another great set of FREE packet tracer labs for the CCNA, check out Neil Anderson's lab guide here: jeremysitlab.com/ccna-lab-guide
so in this case you dont advertise the isp network like the 100 and the 200 network? i tried advertising them and i couldnt figure out why the tunnel kept going up and down. took them off and it was fine.
Yeah don't advertise the connections to the ISP network over EIGRP. It causes a 'recursive routing' error if the tunnel destination address is learned through the tunnel itself. Here's an explanation from Cisco: "In this situation, the best path to the tunnel destination is through the tunnel interface; however, this occurs: The packet is queued in the output queue of the tunnel interface. The tunnel interface adds a GRE header to the packet and queues the packet to the transport protocol destined to the destination address of the tunnel interface. IP looks up the route to the destination address and learns that it is through the tunnel interface, which returns the packet to Step 1 above; hence, there is a recursive routing loop."

do we have to configure for SP routers? If yes that what are the network??
What is the password for SPR1 and SPR2? Please
