Could someone refresh my memory about best practices with loopback interfaces and routing protocols? I starting to roll out a routed access layer design and am trying to figure out the best way to structure my loopback IPs. I need to create a /32 for every switch on my network correct? Even for the ones that are layer 2 and connected to a router or routed access layer switch? I'll advertise the loopback addresses on the router or routed access layer switch, correct?
