A network administrator wants devices in two separate broadcast domains to communicate with each other on the same multilayer switch. What configuration is required to allow communication between these separate networks?
Enable spanning tree protocol on both broadcast domains.
Configure trunk links between the switch and the devices.
Assign IP addresses to virtual interfaces and enable routing on the switch.
Implement port aggregation between the two broadcast domains.
To enable communication between devices in different broadcast domains (such as VLANs) on a multilayer switch, the administrator needs to assign IP addresses to Switch Virtual Interfaces (SVIs) and enable routing on the switch. This creates Layer 3 interfaces that allow the switch to route traffic between the different networks. Configuring trunk links or enabling spanning tree protocol does not facilitate routing between separate networks. Port aggregation combines multiple physical links into one logical link, which does not enable communication between different broadcast domains.
