A important price while in the show standby command may be the precedence. The default is one hundred, as well as router with the highest priority will be the Key HSRP router. We’ll increase the default precedence on R2 and find out the final results. R3 is at present the Lively router and R2 the standby, so Permit’s elevate the precedence on R2 and find out what comes about.
R2(config)#interface ethernet0
R2(config-if)#standby five priority one hundred fifty
R2#exhibit standby
Ethernet0 – Team 5
Neighborhood condition is Standby, precedence one hundred fifty
