Meraki MS and MX DHCP,Vlans Setting

We have one client purchase 2 MX64 and 1 X MS250 For the beginning i design to create the vlan2,3,4 in MX and also DHCP.

My thinking is we have the 2 unit MX64 so i can configure as warm spare.if one unit MX is down so another MX will be can active and all the function will not impact to user.

But recently we receive msg from customer IT team .They would like configure VLANs in MS250 and throw the default route to MX .

May i know what are the benefit to configure DHCP and inter-vlan in switch and please advice which method is better

Hi YaYangTeah,

If you can take the MX64's back I would...they only perform SPI (Stateful Packet Inspection), which is a 1996 technology for packet inspection. In order to protect your network from the current threat landscape you need to be running DPI (Deep Packet Inspection) on unencrypted packets and DPI-SSL on encrypted packets. I would get a NGFW (Next-Generation Firewall) like a SonicWALL TZ400 that will give you higher throughput, better security (DPI, DPI-SSL & network sandboxes), and allow you to do hardware fail-over/fail-back in real-time.

My thinking is we have the 2 unit MX64 so i can configure as warm spare.if one unit MX is down so another MX will be can active and all the function will not impact to user.
The users will definitively incur downtime so if this is a require again I'd recommend a true HA (High Availability) solution as I mentioned before. The MX64 does not support HA/Hardware Failover. So even if you were onsite 24/7 in shifts there would be downtime because you'd have to troubleshoot to determine what is the cause then once realized physically take down the network and setup the warm standby (assuming you are considering a warm standby as it is a cold standby with a copy of current configuration loaded).

If you are in a domain-joined environment and over 20 users then I'd definitely recommend using Windows DHCP server as your primary DHCP server opposed to networking equipment. Inter-VLAN in the switch vs the firewall really depends on a few things: do you require packet filtering between the VLANs...if so then you must do it in the firewall. The second items is can the firewall handle the switching traffic...is the backplane robust enough? You need to determine this and if the firewall can then this is your decision tree to do so.

Let me know if you have any other questions!
