Cisco CCNP / https://en.search.wordpress.com/?src=organic&q=토토사이트 BCMSN Exam Tutorial: Shifting The Lively Router In HSRP

To move the BCMSN exam and gain your CCNP certification, you’ve bought to find out HSRP inside of and out. Though the Procedure and primary instructions of HSRP are fairly very simple, there are 사설사이트 some crucial information which have been conveniently disregarded but are critical in obtaining HSRP to operate the way in which you wish it to. Let’s take a look at using the precedence command effectively on both the Test and in manufacturing networks.

A key worth during the exhibit standby command would be the priority. The default is a hundred, plus the router with the best precedence would be the Major HSRP router. We’ll increase the default priority on R2 and see the final results. R3 is presently the Energetic router and R2 the standby, so Permit’s elevate the priority on R2 and see what transpires.

R2(config)#interface ethernet0

R2(config-if)#standby 5 priority a hundred and fifty

R2#exhibit standby

Ethernet0 – Team 5

Local condition is Standby, precedence 150

Hellotime 4 sec, holdtime twelve sec

Virtual IP handle is 172.12.23.10 configured

Energetic router is 172.twelve.23.three, priority one hundred expires in eight.072

Standby router is area

one condition alterations, last condition change 00:fourteen:24

R2 now has an increased precedence, but R3 continues to be the Lively router. R2 won't get about as being the HSRP Main until eventually R3 goes down – OR the preempt selection is configured on R2.

R2(config-if)#standby 5 precedence 150 preempt

1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Group five condition Standby -> Active

Community point out is Energetic, priority 150, may perhaps preempt

Standby router is 172.12.23.3 expires in ten.204

Virtual mac tackle is 0000.0c07.ac05

two condition changes, final point out transform 00:00:thirteen

In just a few seconds, a information appears the regional state has transformed from standby to Energetic. Clearly show standby confirms that R2, the area router, has become the Lively router – the principal. R3 is now the standby. Therefore if anybody informs you that you've got to take a router down to change the Active router, they’re Improper – you simply should utilize the preempt solution within the standby priority command.

Yet another very important Element of HSRP configurations is knowing tips on how to alter the MAC address on the virtual router, along with interface tracking. We’ll examine Individuals options in the next A part of my HSRP tutorial!
