Question NIM w/ two network interfaces
Hi all, this is my first post on this forum. My main problem is this:

I have a NIM server that I am trying to configure two interfaces on. One interface is for an internal Admin VLAN, the other is so that the server can use SUMA to pull updates. The problem is that I need help w/ the routing. I have made a few mistakes doing this. I want to force all 10.x.x.x traffic over the Admin VLAN and everything else can go over the SUMA interface. That way all of the other AIX boxes and admins can come in on en4 and SUMA and all other packets go to the en8. I used route add and when i rebooted I lost all of my routing, I know that it isn't persistent now! I have used smitty to do a lot of the changes the problem w/ that is that it puts multiple entries into the ODM. Not good messes up the routing table. Here is what I have right now:

Route Tree for Protocol Family 2 (Internet):
10/8 10.156.40.1 UG 5 3660 en4 - -
10.155.40.0 10.155.40.16 UHSb 0 0 en8 - - =>
10.155.40/24 10.155.40.16 U 0 1 en8 - -
10.155.40.16 127.0.0.1 UGHS 0 1 lo0 - -
10.155.40.255 10.155.40.16 UHSb 0 4 en8 - -
10.156.40/24 10.156.40.20 U 1 107459 en4 - -
10.156.40.20 127.0.0.1 UGHS 5 77 lo0 - -
10.156.40.255 10.156.40.20 UHSb 0 4 en4 - -
127/8 127.0.0.1 U 13 171177 lo0 - -

I just need to force all 10.x.x.x over the internal en4 interface, shouldn't be that hard right? Yet I need both interfaces to know where their default gateways are... Maybe I am just missing a step, that is what I am thinking. Any help would be great.

aoe-interfaces

aoe-interfaces(8)					      System Manager's Manual						 aoe-interfaces(8)

NAME

       aoe-interfaces - restrict aoe driver to specified network interfaces

SYNOPSIS

       aoe-interfaces [dev1] [dev2 ...]
       aoe-interfaces -c

DESCRIPTION

       The  aoe-interfaces command tells the aoe driver to ignore ATA over Ethernet (AoE) traffic on all but the specified network interfaces.	It
       is analogous to the aoe_iflist module load option.

       If neither the aoe_iflist module load option nor the aoe-interfaces command are used, the aoe driver will use any network interface for AoE
       traffic.   Using  aoe-interfaces  to limit AoE to only trusted networks prevents the case where a rogue AoE target appears on a public net-
       work, diverting data from the legitimate AoE target.  Such an imposter target effectively corrupts the data on the legitimate target.

       If the aoe driver is a module, then calling aoe-interfaces without arguments will display the current interfaces list.  If it  hasn't  been
       set then the output will be blank.

       It's good to run the aoe-discover command after setting the AoE interfaces list.

OPTIONS

       -c     The -c flag will clear the interface access list, permitting any interface to be used.

EXAMPLE

       In  this  example, the root user on a host named nai loads the aoe module with only eth0 allowable for AoE traffic.  After remembering that
       shelf 7 is on eth3, this sysadmin uses aoe-interfaces to add eth3 to the list of allowable network interfaces and then  calls  aoe-discover
       to ask the aoe driver to look for new AoE devices.

	      nai:~# modprobe aoe aoe_iflist="eth0"
	      nai:~# aoe-stat
		 e10.9		  eth0		    up
	      nai:~# aoe-interfaces eth0 eth3
	      nai:~# aoe-discover
	      nai:~# aoe-stat
		  e7.0		  eth3		    up
		  e7.1		  eth3		    up
		  e7.2		  eth3		    up
		  e7.3		  eth3		    up
		  e7.4		  eth3		    up
		  e7.5		  eth3		    up
		  e7.6		  eth3		    up
		  e7.7		  eth3		    up
		  e7.8		  eth3		    up
		  e7.9		  eth3		    up
		 e10.9		  eth0		    up
	      nai:~# aoe-interfaces
	      eth0 eth3
