We have some 7609 doing broadband aggregation. All fitted with single RSP
in chassis but with inter chassis redundancy. As far as I can remember, we
haven't had any hardware failures with the RSP720-3CXL units in the past
3-4 years. The software on the other hand has been buggy. I'd upgrade to at
least 12.2(33)SRE4 if you plan on deploying. Realistically, more
complexity/features usually lead to unknown/known bugs popping up all over
the place. In the end, the justification for doing intra, inter chassis
redundancy or a combination depends on what you're going to use the setup
for and what SLA's you have with your customers.
