To be perfectly honest, I have been burned so many times by NOT having the subnets keyword that I always use it when classful protocols are involved. The only case I can see where it might cause problems are during especially messy conversions with multiple classful protocols running, AND being forbidden (as in the CCIE lab) to use static blackhole routes.
Indeed, one major conversion design I did started with 2500+ routers, not all Cisco, running a mixture of IGRP and RIP, with the intention of moving the whole mess to OSPF. Ironically, only about 400 of the routers actually needed dynamic routing anyway. The remainder were edge routers that only needed static or floating static routes for default. Another reminder of the recent statement by a CCIE program manager that the CCIE exam is not a design exam, and it's important to do what they ask, not what is the best current practice. >(REPOST) > >I have a question regarding the "subnets" keyword for redistribution: > >I have recently been presented with a scenario by a CCIE - the question >goes: to redistribute the two static routes into a EIGRP router (one is >10.1.1.0 /24 & other is 10.2.2.0 /24) - and the router only runs EIGRP >process.
