Hi Guys,   Can Anyone tell me this design is fine or need some optimization.   Old setup: We have single ISP and one MX. Total four switches in which two are stacked and two are standalone. Currently all the switches are directly connected to MX1.   Now we are adding one more MX in the setup for HA. Here we are going to connect WAN connection through WAN switch to distribute the WAN connection on both the MX. One direct cable connection in between the both MX. All switches are directly connected on the both MX. All the switches are being used as access switches and all vlan gateway on MX. In the warm spare we are using WAN VIP.   Here we are going to do this setup, does it work or need to change in this design as I read somewhere that stp will create problem and asymmetric routing could happen in this.     Appreciated your response and thanks in advance.     ...
