When you specify a broadcast interface as part of a static route in IOS, you
force the router to ARP for every non-local destination in that direction.
Thus, the upstream router must support proxy arp and must itself have a
route to the destination...

Subject: Static route and exiting interface
Hi,
I have a problem to add a static route via exiting interface. If i give it
next hop ip, it will work. Why?
(1) Use next hop ip address:
...
ip route 209.85.173.104 255.255.255.255 24.239.17.25
..
VanVPN#ping 209.85.173.104
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 209.85.173.104, timeout is 2 seconds:
!!!!!
(2) Use local exiting interface:
...
ip route 209.85.173.104 255.255.255.255 f0/0
..
VanVPN#ping 209.85.173.104
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 209.85.173.104, timeout is 2 seconds:
.....
Troubleshooting:
(1) when use exiting interface, i see in arp as below.
VanVPNr# sh ip arp
Protocol Address Age (min) Hardware Addr Type Interface
...
Internet 209.85.173.104 0 Incomplete ARPA
Internet 24.239.17.11 - 0019.0618.6fb0 ARPA FastEthernet0/0
Internet 24.239.17.25 228 00a0.8ea5.2ea0 ARPA FastEthernet0/0
Please help what i did wrong!
Thanks,
Josh
