Nope, no Knuth-like bounty, but maybe there should be! CiscoPress doesn't do
a great job with erratas (erratum?)
I bet it's a minor technical error that the author and tech editors didn't
notice. Maybe they had a shut interface or something when they did their
config (like we're discussing on that other thread. :-) Or, more likely,
they missed a line when typing in their config.
Is the problem that you have 141.108.2.0/27 on R6, but they don't? You
removed the original question so it's hard to follow the discussion. I think
that's what it was though. If there's no explanation for why it's missing,
I bet you can safely assume it's an error. You should report it to Cisco
Press, but that might not do any good.
