Take the tour ×  I want to enable my linux-kernel to passively
listen (learn) the arp request broadcasted in the lan segment
(arp request in the network not destined for me). Is there any
configuration available?  share|improve this question What do
you want to do with this information? Merely for logging
purposes, or do you want to forward with these entries? If you
want forwarding, how many differen tsubnets are attached to this
ethernet interface? –  Mike Pennington Jun 28 '12 at 12:19 does
it matter anyway what I want to do with the information? – 
sahil Jun 28 '12 at 12:46 I tried this without VRRP. I connected
3 routers in a lan. now i sent an arp request from the first
router to second routers. Now both get each other's mac-address.
Meanwhile tcpdump was running on the router3 and I could see
that the arp-request went to router3 also but it didn't updated
its arp table. I want it to passively listen and learn. All the
routers have linux kernel. –  sahil Jun 28 '12 at 13:12 The
