Hi everyone, I wonder how Cisco Meraki can implement LACP on MX series router, when enterprise grade networks relay on high availability requirements. Two switches (Stacked or vPC) share the same connectivity and availability, but have only one Uplink to the WAN devices.   Connecting a second interface Spanning-Tree has to have a Alt Block port of any kind in order to prevent loops. Failover times are up to 35sec (RSTP on normal circumstances) and troubleshooting easy.   This is a perfect enterprise level SD-WAN solution, with a little bit of salt. I hope Meraki will address this issue and perhaps some OSPF timer inconsistence as well.  Remark: LACP does only increase bandwidth when proper hash method (Src. & Dst. Mac's) is distributed.
