so, say you end up with a /24 and your ASN
split up your /24 into hq-/25 and colo-/25
=20
from colo:
1) announce /24 as a standard adv
2) announce colo-/25 with *no-export* community set
from hq:
1) announce /24 as a standard adv
2) announce hq-/25 with *no-export* community set
Run iBGP over a dedicated link b/w colo and hq (I don't like allow-as in! b=
ut it is another option)
