ip helper address for secondary dhcp

[chomunsu]

Is there any way to configure failover dhcp server? I have two dhcp configure for failover but it can be use due to the ip helper address only point to primary dhcp.  is there ip helper address with secondary?

You can configure 2 IP helper addresses on each VLAN interface (well, you can configure a lot more, but you need 2).

It can be done only for one server. If I try to add another, it took the place of the first dhcp server. I try it on HP7510.

dhcp relay server-group 1 ip 192.168.10.110
dhcp relay server-group 2 ip 192.168.10.111

interface Vlan-interface14
ip address 10.0.4.1 255.255.255.0
dhcp select relay
dhcp relay client-detect enable
dhcp relay server-select 2
