Hello Luis,

That document is rather sparse when it comes to detailed information on Cascading contexts.  Are there any documents that go into more details?

In particular I am looking for packet processing information. If you have multiple contexts that have their outside interfaces connected to a "Gateway Context" is Inter-Context traffic processed entirely by the ASASM and does not hit the switch?

Im comparing this to a standard configuration in which multiple contexts would have their Outside interfaces connected to the switches MSFC. In that configuration I would think that the switch would need to process the packets as they egress the outside interface of one context and ingress the outside interface of another.

I would see how in either scenario the switch would process the Layer-2 switching. In the 1st example I would not expect the switch to have to process the Layer-3 traffic as its routing between 3 different contexts on the same ASASM and not having to route down to the MSFC.

Thank you.

Edit:

Just thought of something else I had on my mind.  Would it be possible to run EIGRP between cascading contexts when running ASA Version 9.0(1)
