HSRP load balancing? default gateway redundancy.

[llukman.halimi]

I know that you have to create Vlans in order for one vlan to use one router and the other vlan to use the other router for load balancing per subnet. My question is why do we have to create VLAN's can't we just create 2 Hsrp groups with 2 different virtual IP addresses and set a virtual IP address on half of the hosts and the other virtual IP address on the other half without having to use VLAN's and just letting it be one subnet.

Why must we use VLAN's?

Hello,

yes you can create two standby group with different virtual IP within same interface.

Have a look at GLBP as another option instead of HSRP

Hello in this case the configuration you mentioned also works by groups, but remember that the idea of ​​the vlans is that you can implement in a single link all the subnets, and if you only occupy groups you will only have subnets by physical links.

You can if your device support mHSRP.
