Cisco CCNP / BCMSN Test Tutorial: Changing The Active Router In HSRP
To go the BCMSN exam and receive your CCNP certification, you’ve acquired to find out HSRP inside and out. Even though the Procedure and basic commands of HSRP are really uncomplicated, there are a few critical aspects which might be quickly neglected but are essential in getting HSRP to work the way in which you wish it to. Permit’s Consider using the precedence command appropriately on each the Test As well as in production networks.
A crucial price from the exhibit standby command could be the precedence. The default is one hundred, plus the router with the best precedence would be the primary HSRP router. We’ll raise the default precedence on R2 and find out the effects. R3 is at present the Lively router and R2 the standby, so Allow’s raise the priority on R2 and find out what transpires.
R2(config)#interface ethernet0
R2(config-if)#standby five 안전공원 priority a hundred and fifty
R2#present standby
Ethernet0 – Group 5
Local condition is Standby, priority one hundred fifty
Hellotime four sec, holdtime 12 sec
Upcoming hello there sent in 0.896
Digital IP deal with is 172.twelve.23.ten configured
Energetic router is 172.twelve.23.3, precedence one hundred expires in 8.072
Standby router is community
one point out adjustments, previous point out transform 00:fourteen:24
R2 now has the next priority, but R3 is still the Lively router. R2 will not consider above as being the HSRP primary until eventually R3 goes down – Or maybe the preempt alternative is configured on R2.
R2(config-if)#standby five precedence 150 preempt
