📖 What is Directly Connected Static Route?
A static route configured specifying only the outgoing exit interface instead of a next-hop IP address.
"Be careful using exit interfaces on multi-access networks (like Ethernet) because the router will ARP for every destination, causing excessive traffic and large ARP tables. Use fully specified routes instead."

Troubleshooting high ARP traffic on an Ethernet segment caused by directly connected static routes.
❓ Frequently Asked Questions
When is it best to use a directly connected static route?
They are best used on point-to-point interfaces like serial links where there is only one possible next device.
What happens if you use it on an Ethernet interface?
The router will send an ARP request for every single destination IP, relying on Proxy ARP from the next router, which is inefficient.
