What I've discovered is that the interfaces do not track 1:1. That is, eth0 doesn't always = Mg0/0/CPU0/0 and eth1 does not always = gi0/0/0/0, and so on. The easiest way I have discovered to track which vbox int = which XRv in is to setup both with the intended IPs, and ping, one int at a time, to the far side, while connecting eth ints. Eventually, pings work, though frequently not when the expected ethernet interfaces are attached. Take note of which "eth" = which "gi0/0/0/x" interface and keep going.

I'm assuming that there's an easier way to do this with the port numbers of each int in vbox. Does anyone know of a better way to determine which vbox int is tied to which XRv int?

Additionally, rather than tearing out and re-adding all my links, the following seems to work reliably:

VBoxManage controlvm XRv-1 setlinkstate1 off
VBoxManage controlvm XRv-1 setlinkstate2 off
VBoxManage controlvm XRv-1 setlinkstate3 off
VBoxManage controlvm XRv-1 setlinkstate3 on
VBoxManage controlvm XRv-1 setlinkstate2 on
VBoxManage controlvm XRv-1 setlinkstate1 on

VBoxManage controlvm XRv-2 setlinkstate1 off
VBoxManage controlvm XRv-2 setlinkstate2 off
VBoxManage controlvm XRv-2 setlinkstate3 off
VBoxManage controlvm XRv-2 setlinkstate3 on
VBoxManage controlvm XRv-2 setlinkstate2 on
VBoxManage controlvm XRv-2 setlinkstate1 on

Modify the guest name and replace/add/delete the link numbers as needed. This is on a linux host - I have no experience with vbox on windows so wouldn't know where to start there. This is a lot easier than tearing out and re-adding links every time I restart GNS3.

I wish I could give you karma, +1, etc.. This does work so much better then extended pings, delete and reconnect the Ethernet links...

Adding this as the second part of my script that creates my system's vlan interfaces to my breakout switch.

Followed idrees ezzi's video from youtube, tried all the network & adapter types in Virtual box.

Did you turn off/on the links like how 'pieces of eight' from above showed via your command line?

Can each XR ping it's own Interface?

Can you paste the output of 'show config running', and your .net file?

CDP should help. Turn on 'debug cdp packets' on the interfaces of the other routers connected to the XRv. From the CDP updates you'll see from which gi0/0/0/x interfaces the XRv is sending. Layer 2 will work, even if things are mismatched at Layer 3.

Hope that helps..
