https://community.extremenetworks.com/t5/extremeswitching-exos-switch/summit-x460-high-availability-sample-configuration/m-p/52474#M14549 im using RIP v2 and ip forwarding is enabled in X460 . right now i have only 1 unit x460 running . the network is now operational and i just want to add a backup x460 in case the initially installed failed . so what do you recommend ? VRRP ?

Or VRRP?

For L2, you can use STP, SRP, ESRP. For L3, you can use VRRP or ESRP or simply use routing protocal like OSPF.

In case there is any failure on one switch, the other should take up all the traffic.

You may connect stacked x440 to pair of x460 and form a physical loop(Triangular topology). Then, run STP on all switches and run VRRP as redundancy gateway.
