Heres the code snippet I've used to walk a router's MAC table:
snmpwalk -v 1 -c public ${GWADDR} ipNetToMediaPhysAddress \
|grep ${IPADDR} |awk '{print $4}'
${GWADDR} is your router's IP and ${IPADDR} is the target's IP. This
allows you to qets MACs in another network. Would probably only work
for one hop; everything I have tried it on was only a single hop away.
