I have multiple 6500's and the customer wants me to setup multiple levels of redundancy for FWSM. He wants Intra and Inter Chassis redundancy. So 2 FWSM per chassis per 6500.
My question is that for intra chassis i will use one vlan for stateful and one vlan for stateful information, for inter chassis I should use "DIFFERENT" set of vlans for state ful and stateful redundancy??? can anyone confirm this??
Also how can I make sure that there is no unoptimal routing between the switches and the best design possible, any tips or docs would he highly appreciated and i will surely rate this post.
Not sure i fully understand. A single FWSM can only be in a failover pair with one other FWSM.
So if you have 2 FWSMs in the same chassis and these are a failover pair then you can't then pair either of these with the FWSMs in the other chassis ie. it's an either/or.
Either you have a failover pair in the same chassis or you have a failover pair between the chassis's but you can't have both with the same FWSMs.
