What you are talking about isn't really Anycast from the perspective of=
the=20
rest of the world since what you're saying sounds like you'll just be s=
ingle-
homed behind HE.
Regardless of whether you peer with HE in multiple locations or just on=
e, the=20
AS path is still going to be the same and will enter into 6939 at whate=
ver the=20
BGP-closest point is - the Anycast aspect essentially exists only betwe=
en you=20
and HE.
Providing HE are configuring a discriminator across their iBGP routers =
to take=20
the shortest path at entry points you're not directly peered to, the wh=
ole=20
thing should Just Work, sudden topology changes notwithstanding.
