This is the scenario, a Cisco router with 1 VLAN with 2 or more subnets and a DHCP server inside of one of those subnets.
interface Vlan1 ip address 192.168.0.1 255.255.255.0 ip address 192.168.1.1 255.255.255.0 secondary ip address 192.168.2.1 255.255.255.0 secondary ...
Let's say the DHCP server is inside the subnet 192.168.0.1/24.
Will the DHCP server be able to broadcast to all clients inside all the subnets?
Will clients be able to do UDP broadcasts to all the subnets?
Will clients be able to communicate with clients in another subnet without problems?
