Is it possible to have more than one Ip per VLAN Interface? It is something like IP aliasing.

Yes you can configure multiple ipaddress for a single vlan.
You need to add it as secondary ipaddress.

Example:
configure v1 ipaddress 10.1.1.1/24
configure v1 add secondary-ipaddress 20.1.1.1/24

Yes it’s possible to configure more than one IP per vlan and this is called IP Multinetting.

Please refer - EXOS_User_Guide_16_1.pdf on page number # 1332.

Here's a link to the HTML version of the IPv4 Multinetting chapter from the EXOS User Guide: http://documentation.extremenetworks.com/exos/EXOS_All/IPUnicast/c_ipv4-multinetting.shtml

If I do DHCP relaying, will secondary IP do DHCP relaying too? I want to expand my exhausted DHCP pool of a VLAN but I cannot just resize the subnet since the adjacent subnet has been used. So I think I can do it by adding secondary IPs with different subnet in same VLAN so the DHCP clients will randomly (or load balanced) get the IPs from primary and secondary subnets. Any tough?
