DHCP-failover is implemented in VyOS:

ewald@jeff# show service dhcp-server
 disabled false
 global-parameters "option unifi-address code 43 = string;"
 shared-network-name int-mgmt {
     authoritative disable
     subnet 172.20.0.96/27 {
         default-router 172.20.0.97
         dns-server 172.20.0.97
         failover {
             local-address 172.20.0.98
             name int-mgmt
             peer-address 172.20.0.99
             status secondary
         }
         lease 86400
         start 172.20.0.100 {
             stop 172.20.0.126
         }
         subnet-parameters "option unifi-address 01:04:AC:14:01:2C;"
     }
 }

Beware if you are trying to get failover working and you are serving DHCP for multiple subnets. There doesn't appear to be a way currently to set failover options at a global level for DHCP, it is set at the subnet level. If you want to enable failover for more than one subnet the dhcpd.conf file will be invalid as it will contain multiple declarations for the same fail over group.

I filed a bug on the Bugzilla bug tracker a while ago, it is here: http://bugzilla.vyos.net/show_bug.cgi?id=634
