[ECOS] eCos- i386-network problem( routing )

[rpai@it.iitb.ac.in]

 hello .....

 I have made redboot of i386 in floppy ,I loaded my application and executed

    I have an application that should capture packet..  i inialized 2 eth
card using config tool .. and in program just called
init_network_devices()... I have connected a system to eth0 using
cross cable and another eth1 to the LAN .

                                                     (LAN bcoz sytem r far )
    sys1 --> cross cable -->[(eth0) Sys2 (eth1)]--> LAN <--> sys3
  (10.168.12.169)    (10.168.12.170) ||  (10.168.12.171)    (10.168.12.172)



  i want my system to sys1 ping to sys3 , it is not happeneing ...

  sys1 is pinging to eth0 ..
  sys1 is not pinging to eth1 ..   here it shows ' host unreachable '

  sys3 is not pinging to eth1 .... it transmists packet ,nothing comes on
the screen I  kept transmitting 40 packets..

  this messsage is apperaing in the redboot
           " arp: 10.168.12.169 is on eth0 but got reply from 0x0017aa34
on eth1 "
  and also " arp: 10.168.12.172 is on eth0 but got reply from 0x0017b334
on eth1 "
	   "  arp: 10.168.12.106 is on eth0 but got reply from 0x0017b334 on eth1 "
        mostly the messages of arp is from sys1 ()



  my doubt -> why the sys2(eth1)(ip 10.168.12.171) is not responding to
sys3 (10.168.12.172)


       is it bocoz i have set for both eth0 & 1 same gateway ....

        is there any routing protocol to be enabled to pass packet through
one eth0 to eth1 another..

  I also enabled the chek box in the INET .. " multicast routing support "
but it showed me error
    when building library....

    so what is the routing protocol in ecos and where is it to be woken ..
     can any one get me a solution........


    thanks
