DHCP pool failover round-robin in Cisco?

[tejasvansh77805]

Hi, is there any way to configure a failover between 2 routers connected to a switch?

I have a Cisco switch which has some VLANS, I´ve already configured subnets and pools in both routers, but both routers are giving IP addresses to each VLAN (giving the same IP to different PCs). I want to know if  can set one router as Master and the other one as Slave, o lowering the priority/round-robin.

Will setting 2 default-routers in each pool work as round-robin?

The quick/easy way to split the DHCP across the 2 routers is to give each router half of the pool to allocate (so exclude half the range on each) - so then they will never allocate duplicates.  The end device will usually choose whichever responds quicker.  If you want to load share then have 2 HSRP addresses (R1 as primary and R2 as primary).  You could give both addresses as gateways (but which gets used is up to the end device).  Or you could have each router give it's local HSRP as gateway so those which get DHCP from R1 use R1 as gateway and those which get DHCP from R2 use R2 as gateway.  In a failure both HSRP will switch to the same router and then they all use the same gateway.
