[ietf79-tech] default route?

[Jim Martin]

Leon,
	My personal preference is to take full routes from all sources so you have maximum control on our side. The usual approach is to allow simple best path, taking everything from everyone, and letting the usual BGP rules take control. However, you then have the ability to apply LocalPref as a knob to make fine adjustments if you need/want to. This works well if a particular site is having problems over one link and you want to force it out the other. It also allows you to set localpref based upon incoming communities, to say, for example, prefer a R&E path over a commodity.
