physical layer problem, or issue with VTP

State change with error (addr flap)
|
physical issue more likely

|
state change with error (moveoverflow)

|
state changes on multicast stub
|
common cause deals with non-RPF traffic that non-designated router sees
an access-list on the non-DR is needed |

Asymmetric routing
|
can result in excessive mac flooding
adjust mac aging time or arp timeout or both |
