[c-nsp] 7200 and the PA-MC-2T3+ or PA-MC-2T3-EC PAs

[Stephen Fulton]

Hi Justin,

WRT MLPPP, the PA-MC-2T3-EC's can offload MLPPP to the card, rather than 
the CPU.  Depending on which NPE is installed, that can make quite a 
difference.  And yes, the 7200's support multi-chassis MLPPP, with the 
proper IOS image.
