I've use it for two things. Mobile backup termination OOB termination In both cases with BGP, because I had 2 hubs, for redundancy. But BGP would be needed in the first case anyhow, as the customer delivers IPs. And helps in the 2nd case, even without redundancy to simplify configuration and keep hub configuration free (no touching on hub, when adding or removing spokes, due to BGP listen/allow). I mean this is what got rebranded under SDN but has existed before, it's just pragmatic and specific. -- ++ytti _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
