Hello.
I need help in configuring routing between NetApp and a pair of two Dell PowerEdge 1950
both are running VmWare ESX 3.5.
My NetApp is a cluster pair of FAS 3020c both running DOT 7.3.2.
So i want to unload cisco 2960G switch by directly attaching esx servers to netapp filers.
Currently i have following setup:
fas1> ifconfig e0b
e0b: flags=0x2d48867<UP,BROADCAST,RUNNING,MULTICAST,TCPCKSUM> mtu 1500
        inet 192.168.1.11 netmask 0xfffffff0 broadcast 192.168.1.15
        ether 00:a0:98:09:8d:f7 (auto-1000t-fd-up) flowcontrol full
fas1> ifconfig e0d
e0d: flags=0x2d48867<UP,BROADCAST,RUNNING,MULTICAST,TCPCKSUM> mtu 1500
        inet 192.168.1.12 netmask 0xfffffff0 broadcast 192.168.1.15
        ether 00:a0:98:09:8d:f5 (auto-1000t-fd-up) flowcontrol full
fas1> route -s

192.168.1.2      192.168.1.12       UGHS        0      279  e0b
192.168.1.11     0:a0:98:9:8d:f7    UHL         0       21  lo
192.168.1.12     0:a0:98:9:8d:f5    UHL         1        1  lo
192.168.1.15     ff:ff:ff:ff:ff:ff  UHL         0      100  e0b
So my problem is that when i try to add route in fas1 i do not know how to specify an NIC
where traffic should flow.  I have esx1 (192.168.1.1/28) sitting behind e0b (192.168.1.2/28)
and esx1 behind e0d.  How can i specify interface in route command ?  If i just add route via
route add 192.168.1.2.  It appears that traffic to esx2 flows through e0b NIC, but i want it to
flow through e0d.
I've attached a picture of what i try to implement.  Maybe i should just put second esx server
into separate C-class network?
