HSRP Flashcards
What is a Hot Standby Router?
Uses Virtual IP (VIP) and MAC to allow auto gateway failovers
Who takes ownership of the VIP in HSRP operations?
The active router
How will the standby router know when to transition to the active router?
When it stops receiving “Hello” messages from the active
How do you configure HSRP
R1(config-if)# standby 1 ip X.X.X.X (X.X.X.X is the VIP)
R2(config-if)# standby 1 ip X.X.X.X (VIP stays the same)
Why is not using preempt bad?
If the priority router is flapping. The standby and active router is switch back and forth.
Do you need multiple standby groups when on the same interface?
Yes,
>standby 1 IP X.X.X.2
>standby 1 priority 110
>standby 1 preempt
>standby 2 IP X.X.X.3
>standby 2 priority 90
