Good afternoon, I have two MX100s in a HA pair, and as of this year they have been failing over constantly. At least two times a week. After digging around I found out the Cisco 3750G has been complaining about flapping. Last Friday I recently read that the MX100s need to have STP setup on the downstream switch. Would that be the L3 switch I'm using for routing? Here are the errors. *May 1 13:40:23.462: %SW_MATM-4-MACFLAP_NOTIF: Host cc03.d9e9.45a8 in vlan XXX is flapping between port Gi1/0/2 and port Gi1/0/1 *May 2 19:22:13.258: %SW_MATM-4-MACFLAP_NOTIF: Host cc03.d9e9.45a8 in vlan XXX is flapping between port Gi1/0/2 and port Gi1/0/1 *May 3 03:51:52.852: %SW_MATM-4-MACFLAP_NOTIF: Host cc03.d9e9.45a8 in vlan XXX is flapping between port Gi1/0/1 and port Gi1/0/2 *May 3 14:16:36.967: %SW_MATM-4-MACFLAP_NOTIF: Host cc03.d9e9.45a8 in vlan XXX is flapping between port Gi1/0/2 and port Gi1/0/1 This show it is setup. SWITCHES > L3 ROUTER > MX100 > Cisco 3750G > ISP Both meraki's have a public IP, VIP has it's own public IP. They are all on the same subnet. Any help, or suggestions would be appreciated.
