Our 150 remote routers were all stubbed in our FR hub/spoke network. Now we've migrated 16 over to Metro E/fully meshed network and they are still stubbed. We've kept the FR connections for a backup to the Metro E. The Cisco document "EIGRP Stub Routing" lists the following under Restrictions: "A stub router should not have any EIGRP neighbors other than distribution routers. Ignoring this restriction will cause undesirable behavior." Can someone elaborate on the "undersirable behavior" and whether routers in a fully-meshed Metro E should be stubbed. ATT says they should not. I haven't able to find anything in writing to really define the best practice in this mixed environment.
I have this problem too.
