[j-nsp] BGP export policy, group vs neighbor level

[Andrey Kostin]

I agree, there is no clarity for all possible situations and from my 
experience a) and c) should be correct and take special care. Changing 
existing policy doesn't drop a session (usually ;) and I saw when adding 
a new policy in the existing policy chain didn't drop BGP, but might be 
not always the case. If the router is RR may also affect it's behavior, 
I think almost every network engineer was hit by this Juniper "feature".

Kind regards,
Andrey
