Thread Index [isp-bgp] Re: Routing Information
Thanks for the quick reply. Actually I'm thinking about not having the floating route. If the router cannot see the internal switch and it's local neighbor router it has nowhere to send the traffic so I figure it should not be advertising. I see everyone always recommending a floating route but I figure that could give me a type of local blackhole. Am I missing something?
