Hi Philip,   As far as the Cisco Meraki documentation guidelines, the direct L2 link (VRRP/HA) between the MX design got retired it seems. Are we in a same page? If not, shall we proceed to interconnect a dedicated layer-2 link for MX heartbeat link?   Also, can we use the MX WAN interfaces (/29 IP subnet & same broadcast domain) to have VRRP heartbeat communication for define the failover provided the MXs are deployed in routed mode.   If you could reply for this query, it would really great for our requirement.  ...

Thanks for the quick reply Philip.   I am sorry if my question is wrong!!!   In such case, whether the vMX100 form factor can't be used in a SD-WAN use case?  ... View more

Hi,   What would be the marketplace MX form factor to accommodate 1500+ clients to enable SD-WAN in public cloud like Azure/AWS/GCP?   I understand vMX100 is the current option for public cloud. Just wanted to know Meraki's view to meet such requirments. ... View more

Hi,   Can one of you kindly answer my query regarding the MX250 HA setup in "routed-mode"?   We do have a dual hand-off model Internet link with /29 IP subnet for HSRP mode of fail-over from ISP. We would want to use the WAN ports to participate VRRP heartbeat packets to define the failover since the WAN1 & WAN2 be part of same broadcast domain and moreover ISP routers and MX WAN connections are a local LAN within Data Center.   Is that something possible in MX? If yes, should we proceed to use a VIP in WAN or not?   As a note, we had single LAN connections in each MX LAN ports as a downlink and they are effectively being used for VRRP but when the downlink goes down we end up facing Active/Active role for both MX kits. ...
