DHCP option 191 HEX with 2 IP address

Hi,

I have a question. I will enable DHCP option 191 with 2 IP address. I can set 1 IP address. 

This is my dhcp config:

config system dhcp server edit 1 set ntp-service local set default-gateway 10.6.34.1 set netmask 255.255.255.0 set interface "lan" config ip-range edit 1 set start-ip 10.6.34.30 set end-ip 10.6.34.70 next end set timezone-option default set option1 191 '0a01221d' set dns-server1 10.1.34.60 set dns-server2 10.1.34.61 next end

The Cisco command for option 191 is: option 191 ascii pool1=10.1.34.22,10.1.34.29;level=2

Does anybody know how to do it?

Thanks a lot

Regards
