A critical worth from the exhibit standby command is definitely the priority. The default is one hundred, as well as router with the very best precedence will be the Key HSRP router. We’ll elevate the default precedence on R2 and see the final results. R3 is at this time the Active router and R2 the standby, so Allow’s elevate the precedence on R2 and see what occurs.

R2(config)#interface ethernet0

R2(config-if)#standby five priority 150

R2#present standby

Ethernet0 – Group five
