help experienced seniors!!!!IP aliasing

i have these commands to create an alias of my eth0..

Code:

---

/sbin/ifconfig lo 127.0.0.1
/sbin/ifconfig eth0 up
/sbin/ifconfig eth0 172.16.3.1
/sbin/ifconfig eth0:0 172.16.3.10

---

but when i type this command..

Code:

---

/sbin/route add -net 127.0.0.0

---

i got this ERROR message..

Code:

---

SIOCADDRT: Inavalid Argument

---

these should be the later command..

Code:

---

/sbin/route add -net 172.16.3.0 dev eth0
/sbin/route add -host 172.16.3.1 dev eth0
/sbin/route add -host 172.16.3.10 dev eth0:0
/sbin/route add default gw 172.16.3.200

shouldnt that be 127.0.0.1 ?? ( 1 instead of 0 ) ..

..still i recieve the same error message..
..what else should i do??
..do i have to enable something or should i compile my kernel??

hey.. weven i tried to do the same thig.. but it was not working.. iwalso got the same error. i am using red hat linux enterprise...
but then i changed my technique.. i decide to create Ip aliases using a more general approach..

go to /etc/sysconfig/network-scripts
create "ifcfg-eth0-range0" with the following contents

IPADDR_START=172.28.12.100
IPADDR_END=172.28.12.120
CLONENUM_START=0


creates ip aliases in the specified range... i thought this to be a better way of creating ip aliases. this way i can avoid having to set the route for the new aliases

Edit /etc/network/interfaces and create your alias' there and then restart the network daemon.
