Hello all, Thank you for your response. But I have this thing bugging me for many days now, Please have a look at this : I have connected the ethernet card of two computers with a crossover cable. The ethernet cards are assigned ONLy their inet addresses. NO BROADCAST ADDRESS is configured. and there is no other address on these cards (no gateway, etc) other than their inet address with a netmask of 255.255.255.255( a.b.c.d/32) Then I have added each others eth card as neighbours using "ip neigh add" comand. Then I created a route between these 2 interfaces using "ip route add dest_addr scope link dev eth0(Dest_dev) "(I created the route on both the computers) But when I give the ping commnad with each others Ip address, it doesnt work and gives an error "Destination host unreachable" Have I forgotten to do something? Or is it a problem with iproute2 on my computers which are running on RedHAt 7.1 ? (I have also set the proc/sys/net/ipv4/ip_forward file to 1 ) AND ONE MORE QUESTION: How much time des it take for the zebra daemon to run? (a few seconds or some minutes)? When I ran zebra, there seemed to be no activity. What could be the problem? When the zebra daemon runs, does it display any messages? Please reply, Regards, Sanjeev. __________________________________________________ Do You Yahoo!? Send your FREE holiday greetings online! http://greetings.yahoo.com
