DHCP Server Fundamentals: One Pool

Bundle lab · $29.99

Build a single-scope DHCP server on an IOS-XE router and verify two Alpine Linux clients lease addresses dynamically across a pure Layer-2 switch. Configure only the canonical pool (network + default-router). Verify leases from the router and from each client.

Learning objectives

Configure a basic IOS DHCP server with one pool using network and default-router

Understand pure Layer-2 switching versus Layer-3 gateway roles

Verify client leases from Linux (udhcpc, ip addr) and from IOS (show ip dhcp pool, show ip dhcp binding)

Troubleshoot common DHCP pitfalls: disabled interface, wrong gateway address, client not requesting

Troubleshooting focus

Client never gets an address: verify router LAN interface is up/up with the correct /24 and the DHCP pool exists

Wrong gateway appears on client: ensure the pool default-router matches the actual interface IP

Bindings do not increment: confirm clients actually run udhcpc after the pool is configured
