CCNA Inter-VLAN Routing: Two Clients Across a Router
Deploy, verify, and troubleshoot inter-VLAN routing with two user VLANs split across two access switches, connected via a central router. This realistic topology illustrates trunk misconfiguration, VLAN assignment, and end-to-end reachability for troubleshooting.
What you'll practice
- Configure access and trunk ports on Layer 2 switches.
- Create and assign VLANs for different user segments.
- Configure routed interfaces on a router for VLAN gateways.
- Verify and troubleshoot trunk allow-list and VLAN transport issues.
- Restore inter-VLAN connectivity between endpoints.
