Switch Redundancy

[tecindia1]

I have 2 network switches at one end Switch 1 & 2 and 2 network switches at the other end Switch 3 & 4. SWITCH 1 IS connected to Switch 3 on a uplink and switch 2 is connected to switch 4 on another uplink using a different media creating are redundant path. If the uplink between switch 1 and switch 3 gets disrupted then automatically the uplink between switch 2 and switch 4 should come up. Please guide how should I go about deploying this scenario

 Make a topology, tell which switch is it and if this connection is layer3 or layer2.  It is very hard do advise only with the information you provided.

is this 1 and 2 stacked ? and same 3 & 4

they all different switches and layer 2 connected, then you need to play with STP and cost

If they are stacking -  you looking Layer2 do the port-channel with Lacp it automatically does the job

If you looking Layer 3, then use OSPF this will be automatically Load-balance between the links

Hi Balaji, 

Thanks for your reply.

Switch 1 & Switch 2 are Layer 3 Stacked 9300 Switches  and Switch 3 and Switch 4 are Layer 2 Switches connected at a remote location. 

I tried to replicate the same on Packet tracer.
