Re: BGP SoO

Antonio,

Let's see the issue from this point of view; what if you have 10 BGP sites
with the same AS number connected back to a provider? (like a Uni with a
public AS number and 10 campuses connected to AT&T) what would you do to get
things done in terms of normal updates? allowas-in or as-override solutions
right? did you notice that you almost killed the native BGP loop prevention
mechanism ? :)
