[j-nsp] Changing the ISO NET ID

[John Neiberger]

I have a couple of MX960s that have the wrong NET and I need to update
them. This is a production network. What is the best way to handle this? Do
I need to disable ISIS first or can I just change the ISO address on
loopback0?

My thought is that I need to disable ISIS, change the ISO address, then
re-enable ISIS. Pretty straightforward, but I thought I'd check with you
all to see if you knew of any gotchas.

Thanks,
John
