Cisco CCNP / BCMSN Examination Tutorial: Switching The Energetic Router In HSRP

A key price within the clearly show standby command would be the precedence. The default is 100, along with the router with the very best priority would be the Key HSRP router. We’ll elevate the default priority on R2 and find out the outcome. R3 is now the Energetic router and R2 the standby, so let’s increase the precedence on R2 and see what happens.
R2(config-if)#standby 5 precedence 150
Ethernet0 – Group 5
Neighborhood point out is Standby, priority one hundred fifty
Hellotime 4 sec, holdtime twelve sec
Upcoming hello there sent in 0.896
Virtual IP deal with is 172.twelve.23.ten configured
Lively router is 184.108.40.206, priority a hundred expires in eight.072
Standby router is community
one condition alterations, past point out change 00:fourteen:24
