Same Internal IP to MX65

Netplace Support — Thu, 14 Mar 2019 18:38:25 GMT

Hi,

I have two 3850 switch in stacking and uplink from each switch will be connected to Meraki MX65 for redunancy.

As I know Meraki doesnt support port bundeling so can I give same IP Address to both ports of Meraki connected to 3850 switch, so if 1 port goes down then other port will take the charge.

The Meraki MX are functioning as layer 2 ports so you don't specifically assign an IP address to a port but to a VLAN interface instead.

Since you're connecting two cables from the 3850's stack to the MX, spanning tree should be blocking one of the ports. If the active port fails, spanning tree will open up the other port and start forwarding traffic.
