Cisco CCNP / BCMSN Examination Tutorial: Modifying The Active Router In HSRP
To move the BCMSN exam and make your CCNP certification, you’ve received to be aware of HSRP within and out. While the Procedure and primary instructions of HSRP are very very simple, there http://query.nytimes.com/search/sitesearch/?action=click&contentCollection®ion=TopBar&WT.nav=searchWidget&module=SearchSubmit&pgtype=Homepage#/먹튀검증 are numerous significant particulars which are quickly disregarded but are essential in getting HSRP to operate how you'd like it to. Enable’s Have a look at using the precedence command effectively on each the Test As well as in output networks.
A important price during the present standby command will be the precedence. The default is one hundred, as well as router with the highest precedence would be the Key HSRP router. We’ll raise the default priority on R2 and find out the effects. R3 is at present the Energetic router and R2 the standby, so let’s raise the priority on R2 and see what occurs.
R2(config)#interface ethernet0
R2(config-if)#standby five priority one hundred fifty
R2#clearly show standby
Ethernet0 – Group five
Nearby condition is Standby, priority 150
Hellotime four sec, holdtime twelve sec
Next hello there despatched in 0.896
Virtual IP address is 172.twelve.23.10 configured
Active router is 172.12.23.3, priority one hundred expires in 8.072
Standby router is regional
one state variations, very last condition transform 00:fourteen:24
R2 now has a better priority, but R3 remains the Lively router. R2 will never take around as being the HSRP primary right up until R3 goes down – Or perhaps the preempt alternative is configured on R2.
R2(config-if)#standby 5 precedence 150 preempt
1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Group five state Standby -> Lively
Nearby state is Energetic, priority 150, may possibly preempt
Future hi there sent in one.844
Active router is regional
Standby router is 172.12.23.three expires in ten.204
Digital mac handle is 0000.0c07.ac05
2 condition variations, previous state change 00:00:thirteen
In just a couple seconds, a 먹튀사이트 message seems which the neighborhood point out has transformed from standby to Lively. Display standby confirms that R2, the area router, is currently the Energetic router – the key. R3 has become the standby. Therefore if anyone tells you that you've got to have a router down to change the Active router, they’re Incorrect – you only have to make use of the preempt solution over the standby priority command.
An additional important part of HSRP configurations is recognizing ways to alter the MAC handle on the Digital router, and interface tracking. We’ll look at Individuals attributes in the next A part of my HSRP tutorial!
