[c-nsp] AS override

[Danny Vernals]

Hi Oliver,

I just had concerns over routing table security / integrity but now I think
about it the same issues arise with override as with allowas-in. I think I
can mitigate against these issues with careful design.

Ideally I'd only like to re-write the ASN for certain prefixes that are
matched in a route map matching on community / prefix list etc. However as
far as I'm aware this is not possible?

Thanks for the reply

Danny
