Hi everyone,    I'm trying to use an MS120-8 to split 2 WAN links between 2 MX100s that are in HA. I followed this guide to set up the HA pair using downstream switches in a full mesh config for VRRP.   However, I ran into real issues when I introduced the MS120 between the ISP handoffs and MXs. This is how I had it configured:                                       The first issue was trying to configure the breakout switch. It wouldn't connect to the Meraki cloud without also being directly connected downstream to one of the L2 switches. Without that connection, the LED would remain orange, and the switch shows as offline.   The second issue is I started seeing 'Uplink IP Conflict' errors on the primary MX. I'm not sure why given that, I have statically assigned the WAN IPs on both MXs.    Finally, I also saw a spike in packet loss, where it used to be 0% before introducing switch, it's now consistently 15-20%.    Unfortunately, I don't have a lab environment to test any of this, so to avoid disruption during our business hours, I've partially rolled back to the following setup which appears to be stable for now:    WAN1 - MX1 WAN2 - MX2   MX1 and MX2 in HA via downstream switches per the diagram.    From everything I've read on here, even a simple unmanaged switch should work, so I'm not sure what I'm doing wrong with this MS120. Any help would be much appreciated.    Thanks. Raj ... View more
