dhcpv6 failover issue

I am using dhcp 4.2.2 and trying to do the failover. 


Primary server configuration:

failover peer "fo" {




        port 519;

        peer address;

        peer port 520;

        max-response-delay 60;

        max-unacked-updates 10;

        mclt 360;

        split 128;

        load balance max seconds 2;


shared-network backup{


subnet6 2001:4408:5205:128::/64 {


        range6 2001:4408:5205:128::01 2001:4408:5205:128::FF;


failover peer "fo";



But when I start dhcpd, It shows following error:


[root at Server6 server]# ./dhcpd -6 -cf dhcpv6.conf eth0

failover peer fo: I move from recover to startup

failover peer declaration with no referring pools.

In order to use failover, you MUST refer to your main failover declaration

in each pool declaration.   You MUST NOT use range declarations outside

of pool declarations.


When I configure Pool with range 6, It shows error as "range6 cannot be
used", since I am dealing with Ipv6 only address assignment. How can I use
failover in that case?

Also failover can be used without using shared-network?
