I could be wrong about this, so please provide feedback.
The router doesn't just ARP for the next hop, it ARPs for everything
unless it's a point-to-point link. That implies proxy-arp running at
the next hop. I don't believe you should point a static route to a LAN
interface for this reason.

Subject: Default route pointing to an interface or next hop IP address
Hello group,
Until I now couldn't understand why a default or static route doesn't
always work when pointing to an interface. Been a victim of this a few
times wherein during the staging process it works but on the actual
implementation it doesn't (on some instance it worked). Is there a hard
written rule here when to use the physical interface or not on a certain
scenario ??? I usually encounter this problem with DDR (physical/dialer
interfaces) or HSRP on LAN's. Am I right to say here that when using the
physical interface instead of the next hop IP address, the router would
do an extra sort of an ARP-ing process to resolve the next hop address
???
Appreciate any feedback.
Kind regards,
Neil
