In this configuration, can the ping package be handled by the ndo_start_xmit function of oai0?

the case is that there is a device: on server A

oai0 Link encap:AMPR NET/ROM HWaddr

      inet addr:10.0.1.1  Bcast:10.0.1.255  Mask:255.255.255.0
      UP BROADCAST RUNNING NOARP MULTICAST  MTU:1500  Metric:1
      RX packets:0 errors:0 dropped:0 overruns:0 frame:0
      TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
      collisions:0 txqueuelen:100 
      RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

this is the route:
10.0.1.0 dev oai0 proto kernel scope link src 24 route 10.0.1.1

its ndo_start_xmit function forwards incoming packets to the user process.

as a matter of fact, I did see the log that ndo_start_xmit was processing on ping10.0.1.2 on A.

but on server B, which is connected to A, I add a route:
10.0.1.0 IP) dev eth0
of 24 via (A, and then ping 10.0.1.2 on B. my assumption is that this ping packet will also be processed by oai0"s ndo_start_xmit function, but it doesn"t seem to be.

I grabbed the packet on the interface connected to B on An and showed that the ping packet did come to A, but why wasn"t it forwarded to oai0?

I am a rookie to the linux kernel. Hope to get your help, thank you!
