I'm about to start implementing loopback interfaces and /32 addresses for monitoring and management purposes. My question is what to do about address management. If I assign /32 addresses to each device I can see my routing tables growing quite large, if I summarize them to a /24 and advertise one /24 per site would I not be wasting alot of addresses?
Say I have a site with 10 devices, each with /32 Loopback addresses, and then I summarize this as a /24 across the WAN, I'd be wasting alot of addresses that way.
Does anyone have any suggestions on how to handle this? I find it odd that something that feels pretty crucial, such as management of devices has hardly any published case scenarios or best practices. I can't find much information at all on the subject. Any help would be greatly appreciated.
