%DUAL-5-NBRCHANGE: IP-EIGRP(0) 100

[zinkann]

I have about 5 3560's running EIGRP configured as EIGRP STUB CONNECTED routers, which talk to a core 4506. I am using vlan 1(for now) as a transport vlan. It is a HUB and SPOKE topology with a Metro E ISP. i just plug all of my switches into their switch and they provide me with a vlan so i just plug into it. All of the 3560's use vlan 1 for the routing updates. At those locations i have them set up for intervlan routing. I'm receiving this error on all of them...

%DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 10.0.2.79 (Vlan1) is down: holding time expired
%DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 10.0.2.79 (Vlan1) is up: new adjacency



The 4506 is my core switch which is doing inter vlan routing network wide and i have a lot of dark fiber. I am running EIGRP only on the metro E side so i can have multiple vlans at those locations. If i didn't then they would all be on one subnet because of the ISP. Here is the config from one of the switches....

Why are the access ports shutdown?

They aren't in use. I don't want anyone plugging into them. All i have is a phone and PC at this location.

I was under the impression that in a hub and spoke topology i need to use EIGRP STUB CONNECTED. On the switch, the definition of EIGRP STUB CONNECTED is "Do advertise connected routes". Does that mean that this 3560 will not advertise vlan 58 to my core 4506?
