At first reading, I thought the redacted part was about how to tell if _your_ router was compromised but on closer reading, it looks like it covers routers owned by others that the NSA have cracked but they want to know if the Chinese or anyone else has done the same.
It's interesting how this is boils down to existing malware strategies but with a how to. They're probably not going to type this stuff up in a wiki anymore going forward, shift to in-person training and word-of-mouth.
