I have a series of questions to ask consecutively.
Understanding the general idea of what load balancers do is easy enough. It's the actual implementation and how they fit into an existing architecture that I seem to find somewhat challenging.
I don't have access to a school or any formal training, so I am trying to understand the nuts and bolts of implementation on my own.
May I ask for some help?
Please take a look at this link.
Here is how I interpret the traffic flow.
Incoming-to-outgoing traffic takes this route:
--> In from Internet --> 220.127.116.11 --> 18.104.22.168 --> 22.214.171.124 --> 126.96.36.199 --> back out to Internet
1a) Am I correct?
2a) Is this considered to be a set up in which the LB is operating in routed mode?
3a) In this case, there would have to be layer 2 adjacency between the server farm access layer and the routed distribution layer, correct?
I'll leave it at that for now.
Your'e going to hate me for this but one-armed mode is not bridged.
What i probably should have said is that in one-armed the traffic goes in and out the same interface hence the one-armed bit.
So traffic from the client hits the MSFC, gets routed to the CSM, the CSM nats the destination to a real server and the source to an address that will get routed back to the CSM and then sends the packet back out of the SAME interface.
As for a book the only one i know is
"Designing Content Switching Solutions" by Zeeshan Naseh and Haroon Khan. It is a cisco press book and it is fairly good. It covers both standalone CSS's and CSM's and also how to integrate these with FWSM's etc. in your data centre. It does not cover the ACE module which is the replacement for the CSM.
Might be an updated version now, worth checking.
I'll have a check this week for docs if i get the chance.
