We’ll raise the default precedence on R2 and see the effects. R3 is at the moment the Lively router and R2 the standby, so let’s raise the precedence on R2 and see what transpires.
R2(config)#interface ethernet0
R2(config-if)#standby five priority a hundred and fifty
R2#show standby
Ethernet0 – Group 5
Regional condition is Standby, precedence a hundred and fifty
Hellotime 4 sec, holdtime twelve sec
Next hi there despatched in 0.896
Digital IP tackle is 172.12.23.ten configured
Active router is 172.12.23.three, precedence 100 expires in eight.072
Standby router is regional
1 state adjustments, previous state transform 00:fourteen:24
