A short question I've got from Shahid Rox:

Today I read your article about scaling EIGRP using stub routers. I was wondering whether you can use the leak map only for routes learned from other EIGRP neighbors? Is it also usable to filter connected routes?

Leak-map controls what its name implies: the leakage of routes received from EIGRP neighbors to other EIGRP neighbors. To filter connected prefixes redistributed into EIGRP, use the route-map on redistribute connected command. The only way I've figured out to filter announcements of directly connected networks that are part of the EIGRP process is the distribute-list out command.
