Question about CSM & FSM config

triplecap

I've read the CSM guide and the doc on running the CSM & FSM in the same chassis, but I still have a few questions...

I'm working on the configs for running a FSM and CSM in the same chassis (w/ redundant modules in a separate chassis) with the CSM in bridge mode. The traffic will go from our inet router -> FSM -> CSM -> real server. Since this doesn't involve the MSFC I don't need to worry about HSRP. Can someone please look at the config below to see if I'm on the right track:

module ContentSwitchingModule 4

ft group 1 vlan 930

priority 105 alt 100

heartbeat-time 1

failover 3

preempt

!

vlan 200 client

ip address 10.32.16.5 255.255.255.0 alt 10.32.16.6 255.255.255.0

gateway 10.32.16.1 (an interface on the fsm)

!

vlan 500 server

ip address 10.32.16.5 255.255.255.0 alt 10.32.16.6 255.255.255.0

alias 10.32.16.4 255.255.255.0

My questions are:

1. If I have other servers using the MSFC as their gateway that need to access load balanced servers, do I put routes for the above network pointing to the FSM or the the alias address?

2. Do the load balanced real servers use the FSM interface or the CSM alias as their gateway?

3. Some docs suggest creating the alias on the server vlan and others on the client vlan. If an alias isn't referred to in either of my above questions, do I just not need one in bridge mode?

Thanks in advance,

Eric

Yes, If there are other servers usign the MSFC as their gateway, you have to put routes for the above network pointing to the FSM. The load balanced real servers use the FSM interface as their gateway.

Thanks, that answered most of my questions! What about the alias addresses though? Do I not need an alias if I'm not invovling the MSFC and am only running the CSM in bridge mode?

Thanks again,

Eric
