Hello,
Recently I have been told that some ISP's are automatically or maybe manual=
ly modifying their BGP inbound prefix listing after a network is not advert=
ised to them for a period of time.
So the questions I pose to the group:
1. Is this normal?
2. Can anyone share your policies?
3. Who does it?
4. How often?
5. Is it automagic? Or the dirty work slaved off to the junior engine=
er in the corner somewhere?
a. I know you probably won't trust that junior engineer, but some do.=
...
Anyway just a little research after a small problem a customer recently had=
.
Thanks,
Jim
