hai everybody,

when i type at my shell: tcpdump arp

it shows me a list of arp requests and arp replies are not showing of others "MAC addresses"

After that i type at my shell : arping -b -c 10 -s <src ip addr> -i eth0 <dest ipaddr>

then it gives a mac addr of a particukar ip addr shown earlier with tcpdump arp.

But my doubt is........

Whan i type at my shell:

arping -b -c 10 -s <src ip addr> -i eth0 <router ip addr>
it doesn't give its mac addr (WHY)

pls tell me...........

iam interesting to know about this.......

if anybody knows , pls tell me.........

Thanks
