Trouble configuring WAN with GNS3

veritas_libertas

I'm not sure whether or not this is something I'm doing wrong with GNS3 or just me not knowing what I'm doing setting it up

I cannot get them to ping each other. The line protocol keeps dropping which I'm not sure why.

This config looks good to me, and just to be sure I tested it in GNS3 and there was no problem.

If your dropping line protocol I would check to make sure you don't have an encapsulation mis-match on either interface.

Also, what router type are you using? I have seen issues with the 2600's in GNS3, so it could be something weird with that.

I'm using a 2651XM IOS. The funny thing is, I reloaded the virtual routers and they started working. Very odd behavior.

At least I learned something
