Say I get a /16 and a /24 for a prefix from ISPA with the same next hop so I wouldn't want to install the /24. But what happens if I get a /16 from ISPB and that gets sent to RouterA. That prefix would have a next hop of Router B or ISPB so it would be a different prefix and installed in the RIB. Now the traffic that was originally flowing to the /24 would take the backup path (due to a longest match lookup) rather than the path it would have taken if we had installed the original /24. Would that be acceptable?

Having the next hop requirement as optional would be great. If our routers can handle it then we'd keep as much of the existing semantics as possible (not withstanding Randy's traffic engineering point which is also valid). If that introduces too many longer length entries than we can handle then we flick the switch and drop the longer prefix regardless of next hop. Having that flexibility would be great.

Anyway, what harm can there be in adding one more tuning knob to IOS :-)
