I have a simple question. In hub-spoke, would it be possible to configure all routers including hub as eigrp stub if hub does not to advertise spoke's subnets to other routers (outside of hub-spoke)? Could anyone please clarify it for me?
In general it would not be good to configure the hub router as an EIGRP stub. If there were no router in the Enterprise other than the hub and the spokes then probably it would work. But if there is any other router - any Internet router, or other router at headquarters or anywhere then it is problematic for the hub to be configured as EIGRP stub.
