Configuring Inter‑VLAN Routing on Two Three‑Layer Switches Using Static Routes
This guide demonstrates how to enable communication between hosts on different subnets within the same VLAN across two three‑layer switches by configuring VLANs, assigning IP addresses to Vlanif interfaces, and adding static routes on each device.
Two three‑layer switches are used to connect hosts (PC1 and PC2) that belong to the same VLAN but reside in different IP subnets, requiring static routing for inter‑subnet communication. undo info-center enable On Switch A:
