Cisco CCNP / BCMSN Exam Tutorial: Altering The Lively Router In HSRP
To go the BCMSN Test and earn your CCNP certification, you’ve bought to know HSRP inside and out. Whilst the operation and primary 먹튀사이트 commands of HSRP are very uncomplicated, there are several critical facts which have been effortlessly missed but are crucial in receiving HSRP to work how you want it to. Let’s Look into utilizing the precedence command effectively on the two the Test As well as in manufacturing networks.
A key worth inside the clearly show standby command will be the precedence. The default is 100, plus the router with the best priority would be the Key HSRP router. We’ll increase the default priority on R2 and find out the outcome. R3 is currently the Lively router and R2 the standby, so Permit’s raise the precedence on R2 and find out what transpires.
R2(config)#interface ethernet0
R2(config-if)#standby five precedence 150
R2#display standby
Ethernet0 – Group 5
Regional condition is Standby, precedence one hundred fifty
Hellotime four sec, holdtime twelve sec
Next hello despatched in 0.896

Energetic router is 172.12.23.3, priority one hundred expires in eight.072
Standby router is nearby
