Switch Stacks Routing Interfaces Configuration

Switch Stack Layer 3 Interface Management

Switch stack routing interfaces configuration in Meraki networks provides administrators with comprehensive Layer 3 connectivity and inter-VLAN routing capabilities for stacked switches, enabling VLAN interface creation, IP address assignment, DHCP service management, and OSPF routing integration. This functionality supports network segmentation, subnet routing, multicast forwarding, and centralized DHCP services across the switch stack. Stack routing interfaces are essential for creating routed networks, enabling inter-VLAN communication, providing DHCP services, and integrating with dynamic routing protocols in enterprise network architectures.
