Testing Static Route with no proxy-arp command

R1#sh run | s route

ip route 3.3.3.0 255.255.255.0 FastEthernet0/0

ip route 10.1.13.0 255.255.255.0 FastEthernet0/0

R1#sh ip route | begin Gate

Gateway of last resort is not set

3.0.0.0/24 is subnetted, 1 subnets

S 3.3.3.0 is directly connected, FastEthernet0/0

   10.0.0.0/24 is subnetted, 2 subnets

S 10.1.13.0 is directly connected, FastEthernet0/0

C 10.1.12.0 is directly connected, FastEthernet0/0

Before using no proxy arp on R2

R1(config)#do ping 3.3.3.3

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 52/101/232 ms

NOTE :: In Static Route , we prefer next-hop points to ip address than next-hop points to outing interface or exit interface .
