Layer 3 vlan and hsrp

[networkinggeek]

In my network, and I want to get better understanding of vlan/hsrp/and SVI here

I have a vlan 123, as SVI on two switches pointing to same VIP 192.168.1.1

sw#1>>show running-config interface Vlan123

ip address 192.168.1.2/24

hsrp 123 
preempt
priority 101
timers 1 3
ip 192.168.1.1

sw#2>>show running-config interface Vlan123

ip address 192.168.1.3/24

hsrp 123 
preempt
priority 101
timers 1 3
ip 192.168.1.1

so I have set both as same priority, what I want to know, is there any role of hsrp priority on SVI interfaces?

second say, if I change the subnet config on my second switch to following, so I can do a switch cutover, can thse both  switches work independently without conflicting with each-other, with different subnets??

ip address 192.168.2.3/24

hsrp 123 
preempt
priority 101
timers 1 3
ip 192.168.2.1

Thanks

you meaning that SVI priority to elect one SVI as active and other as standby.
NO since they are the same the first is power up and become active it will still active unless there is preempt, if there is preempt there is special message send to make old active peer to reelect and become as new standby and old standby will become the active.
please visit my page I make video about the HSRP
