secondary vlan ip on EVPN-VxLAN network

I have working EVPN-VxLAN fabric and life is good but now i need more public address so i am planning to add new public IP subnet in existing public VLAN interface on all border-leaf and my other leaf switches. does following work and any other complication for future?

currently i have following config for public VLAN

interface Vlan100 description ** Anycast Gateway For Public ** no shutdown mtu 9216 vrf member CUST1 no ip redirects ip address 69.xx.xxx.1/24 ipv6 address 2600:c04:3111::1/64 ipv6 nd prefix default no-advertise ipv6 nd ra route suppress no ipv6 redirects fabric forwarding mode anycast-gateway 

I want to add new public subnet Ex: 70.xx.xxx.1/24

so can i do following, just add secondary ip?

interface Vlan100 ip address 70.xx.xxx.1/24 secondary
