A important worth from the show standby command will be the precedence. The default is one hundred, as well as router with the highest priority will be the Most important HSRP router. We’ll elevate the default precedence on R2 and see the final results. R3 is presently the Active router and R2 the standby, so let’s elevate http://www.bbc.co.uk/search?q=토토사이트 the precedence on R2 and find out what transpires.
R2(config)#interface ethernet0
R2(config-if)#standby 5 priority a hundred and fifty
R2#present standby
Ethernet0 – Team 5
Neighborhood point out is Standby, priority 150
Hellotime 4 sec, holdtime twelve sec
Following howdy sent in 0.896
Virtual IP handle is 172.twelve.23.ten configured
Active router is 172.12.23.three, priority a hundred expires in eight.072
Standby router is neighborhood
1 point out modifications, previous state modify 00:14:24
