[c-nsp] Replacing route policies in IOS XR

[John Neiberger]

I'm relatively new to route policies in IOS XR. I have a route policy
on a production router that needs to be replaced. The documentation
doesn't exactly make it clear how to do this properly. Is it as simple
as pasting an entirely new route policy in config mode and committing
it? I see that there are methods for editing the policy directly from
the CLI, but that doesn't seem like what I want or need. Since route
policies don't use line numbering, I'm worried that I might end up
with some weird merged policy. If we're just replacing the entire
thing, is it a simple paste and commit?
