Hi all, Turns out it was a bad cable on the heartbeat ports. Replace them, and the failover went away.

Hi cmr, I updated the photo again. VLAN 400 is for our datacenter. The ISP setup a Site to Site VPN that they manage for us. The Aruba switches are Layer 3, so they handle routing. I'm not sure what it was setup like it. I'm just the messenger lol. The MX's are setup as routed mode. Only two VLANs are setup on the MX. VLAN 2 is the "networking vlan" and 1111 is for the "heartbeat".

Hi Kind of a big deal, Still trying to figure that out (mac address wise), but the MX100s are the ones connected to it. I'll post a picture of the physical layout.

Hi cmr, On our Firewalls under Security & SD-WAN > Appliance Status > Uplink The DNS settings are pointing to something publicly. Is that what you are referring to?

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.
