I have a simple network 4 2621's for various uses and a PIX firewall at
the gates. I have in the past just kept a couple extra routers around
so I could test configs/commands before pulling the trigger. I
currently only have one spare and need to make a change on each side of
a T1. I just want to make sure I've got my commands down before doing
it, because it's a 30 minute drive to each side and I have no help. I
was looking around and it looks like for 250, this routersim software
will allow me to program 2 2621's and test router across them. Is that
correct or is there a better software for the roughly the same amount
of cash. It's the company money, but I would feel guilty turning in
$1000 bill to save a few miles. Thanks for your help.

The approach I use in this situation is to use the "in" option on the
reload command

1. type "reload in 30" ! reload router in 30 minutes if not cancelled

2. make config changes

3. test

4. type "reload cancel"



So if something goes wrong the router reloads and the changes are
negated because they are not in the startup-config
