2 IP GATEWAY with same subnet

Hi Guys, Good Evening.

I have a client that has 2 MPLS line with same subnet  like ISP1- 192.168.10.5 and ISP2- 192.168.10.6 and now they were asking if its possible to meraki MX to terminate same gateway ip address so that if ISP1 will go down, ISP2 will take over?

Note: I already ask the client to change the subnet of both ISPs to make it different from each other but they refuse it.

 

Thanks in advance.

Kind of a big deal

I think you're asking if you can have WAN1 and WAN two with IP's in the same subnet? If so, the answer is yes, this works without issue.

 

 

aside from same wan1 and wan2 subnet, i also want to have to 2 ip gateway on the lan interface .

 

By the way, if i my wan1 and wan2 are assigned with same subnet it will be automatically NATed. How can i see my next hop router since it is MPLS line.
