Hello,
We have multiple networks on multiple Cisco switches all using Vlan 1, we need one network to talk with another and ok to add multiple subnets to the 1 Vlan or any Vlan?
Thank you

You can have multiple subnets on the same vlan interface. You'd mark them as secondary ip addresses.
int vlan 1
ip addre 192.168.1.1 255.255.255.0
ip address 192.168.2.1 255.255.255.0 secondary
ip address 192.168.3.1 255.255.255.0 secondary
Although, it's not best practice because typically you'd want one subnet per vlan but this works in a pinch.
