how to specify a subnet of multiple subnet on same int ve to relay dhcp packet at ICX?

Question

Hi Friends.

It assume it configured multiple subnet on a interfce ve 100 and needs dhcp relay at the int ve 100.

Ex. int ve 100, ip add 1.1.1.1/24, ip add 2.2.2.2/24 ip add 3.3.3.3/24

As a rsult of my test, relay agent ip(GIADDRESS) in dhcp packet is 1.1.1.1, the lowest IP address.

At cisco, it has primary ip, his ip address is relay agent ip(GIADDRESS).

But ruckus icx has no primary ip address.

How do I specify 2.2.2.2 or 3.3.3.3 as relay agent ip(GIADDRESS)?

Or not?

Regards.

Did you ever find a solution to this?  I am looking for info on this but for a slightly different scenario.

I have to change the ip scheme I use on my vlans.   I would like to run dual subnets (Old subnet and new subnet) on the current vlan while I switch everything over, eventually removing the old subnet. I would like to control which subnet will be relayed for DHCP request during this process.

Hi Chandini.

I assumed a topology like below.

On above, ICX send dhcp paket with lower ip address as relay agent ip.

Do you understand it?
