Parry,

I agree with you but......

If you read Joseph's criteria, it states advertise a network without using
NETWORK or REDISTRIBUTE command plus advertise only to this one peer. This
would narrow down to advertising a default route to the neighbor.

If you chose to disagree, pl. advise an alternate way to satisfy Joseph's
criteria

You tell your neigh x.y.z.a that your AS is the defaut route for their
network. It sound like
some information is missing. If you don't even know such network within your
AS, how can you
advertise and tell other how to reach that network.

I could be wrong. but how about...

neighbor x.y.z.a remote-as <<backbone as>>
neighbor x.y.z.a default-originate

This *could* be a third way of injecting the *route*. Of course this will
inject a default route, but it is one method that satisfies both of your
criteria (ie. dont use network or redistribute, dont use static, no other
ibgp/ebgp peers should know about this route)

What do you think ?
