Hi,

i need to connect 4000 Series ISR with two layer 3 switches 3650. I want to use redundant path for switch. One switch fail then second remain up,  I have only 6 IP address range that I can use to interconnect these three devices. So how I can use redundancy technology on interfaces to make them works. 

Please help me for this.

How are these switches connected ? 2 Switches stacked or individual.?

Hi, these two switches are individual, this is new setup we are up grading from two 24 ports switch layer 2 to two new 48 ports layer 3 switches. Before we are using trunk for layer 2 switches, this time I want to avoid trunk and here router just do WAN connectivity to these switches...
