LTM multiple interface/vlan routing issue

you are almost completely correct in your capturing of the problem. everything is dead on except the part about server B being local to server A while this may be the case we have not run into that yet. the actuall scenario we are in is below:

 

 

ENVIRONMENT

 

----------------------

 

VLAN 1 = 192.168.1.0/24

 

VLAN 2 = 192.168.2.0/24

 

VLAN 3 = 192.168.3.0/24

 

 

Server B = 192.168.1.11

 

Server C = 192.168.3.10

 

 

BIGIP

 

interface 1.1 = 192.168.1.50

 

interface 1.2 = 192.168.2.50

 

interface 1.3 = 192.168.3.50

 

 

VIP myVip

 

IP = 192.168.2.101

 

port = 80

 

default pool = myPool

 

 

POOL myPool has Server B as its member

 

 

 

SCENARIO

 

-----------------------

 

From Sever C, you are trying to access http://myVip/index.html and it's failing.

 

 

 

i liked your layout of the description sorry i plagerized!

 

 

it seems as though bigip does not like the fact that it received a request on interface 1.2 sent it to the server needed but wants to send the traffic back on interface 1.3.

 

 

FLOW

 

----------

 

from server C ---> into interface 1.2(myVip) ---> out to server B --->returning to interface 1.1 --->out of interface 1.3
