Failed removing routes

[MoshiachNow]

HI,

On AIX 5.2+ML01,I have added a second interface (10.4.27.183)on the same default network (extra to the orinal one - 10.4.27.204).
From now on,I have two interfaces pointing to each host on my network,which I do not want .

netstat -rn
Routing tables
Destination Gateway Flags Refs Use If PMTU Exp Groups

Route tree for Protocol Family 2 (Internet):
default 10.4.26.1 UGc 0 0 en1 - -
10.4.26.0 10.4.27.183 UHb 0 0 en1 - - =>
10.4.26.0 10.4.27.204 UHb 0 0 en2 - - =>
10.4.26/23 10.4.27.183 U 1 9 en1 - - =>
10.4.26/23 10.4.27.204 U 1 67 en2 - -
10.4.27.183 127.0.0.1 UGHS 3 56 lo0 - -
10.4.27.204 127.0.0.1 UGHS 3 63 lo0 - -
10.4.27.255 10.4.27.183 UHb 0 2 en1 - - =>
10.4.27.255 10.4.27.204 UHb 0 2 en2 - -
127/8 127.0.0.1 U 12 236 lo0 - -

Route tree for Protocol Family 24 (Internet v6):
::1 ::1 UH 0 0 lo0 16896 -

In the process of attempting to remove the routes I do not want - I have tried the following:

1.route delete 10.4.26.0 -interface 10.4.27.183

Did it for evey route I did not want,but they all come back after reboot...
2.lsattr -El inet0

authm 65536 Authentication Methods True
bootup_option no Serial Optical Network Interface True
gateway Gateway True
hostname rdev4 Host Name True
rout6 FDDI Network Interface True
route Route True

Did not find anything offending here ...

3.odmget CuAt | grep 10.4.27.183
value = "10.4.27.183"

Looks like the "bad" routes are not even in ODM ... ?

4.no -p -o tcp_pmtu_discover=0
no -p -o udp_pmtu_discover=0

And rebooted - no luck still.

Urgently need ideas how to force the system to remove new routes !
Thanks

Long live king Moshiach !

I am not sure you will ever be able to keep those type of routes out of your routing table given your current configuration. Maybe you should use an etherchannel configuration instead of 2 different adapters with different IP's on the same subnet. I have used etherchannel with great success on AIX 5.2.
