Did Cisco bother to use an editor for the CCNP ENSARI study guide? The book is riddled with grammatical errors.

Just flipped to the chapter on VRF to familiarize myself with how Cisco implements L3VPNs on their equipment. So far the pronoun "it" as been spelled as the abbreviation "IT", and a period in the middle of the following sentence:

"Therefore, each of these virtual networks need to have its own r.outing table to ensure isolation."

Probably minor overall but not impressed with what it says about these published works.
