The SA-VAM does layer 3 compression IPPCP. The AIM-COMP does layer 2
compression. These two modules will not work together. You have to do
comp-lzs as a crypto map on both ends. The SA-VAM will have hardware
accelleration for the 7200, while the 2600 will do it in software. Comp-lzs
is a resource hog, so you will see high cpu utilization on the 2600.
