A essential benefit within the exhibit standby command will be the precedence. The default is a hundred, and the router with the highest precedence would be the primary HSRP토토사이트 router. We’ll increase the default precedence on R2 and find out the results. R3 is at present the Active router and R2 the standby, so let’s raise the priority on R2 and see what happens.

R2(config)#interface ethernet0

R2(config-if)#standby 5 precedence 150

R2#present standby

Ethernet0 – Group 5

Local point out is Standby, precedence a hundred and fifty

Hellotime four sec, holdtime 12 sec
