Also, on recent IOS you can scp *to* the box and it works just like a
"configure network" e.g.

cat <<EOF >config-fragment
interface VlanN
 ip address x.x.x.x 255.255.255.0
 no ip proxy-arp
end
EOF

scp config-fragment router:running-config

You still need to clogin and "wr mem" but it can be easier to push the
actual config changes with this method.
