Just NOOP sliding

It turns out I forgot an interface from SW1 to R5. Below is the new physical overview with accompanying GNS changes.

I’ve also set up the GNS routers with IP’s and associated frame relay commands. See below for the network overview containing IP’s + DLCI’s and the generic + frame relay config for each device.

Like the minicom scripts, I’ve also hardset the GNS console port numbers so I can configure console scripts. It’s very straightforward:

nano br-ccie-frs
telnet 127.0.0.1 2000
chmod 777 br-ccie-frs

Everything is still rolling well. Even though there are no routing protocols or heavy packets running yet, the X2 is handling the 5 routers without a hitch.
