Hello,
In Workbook 2, Lab 10, question 5.2 it asks you to setup MLP LFI between HQ and BR1. In the solution guide it has you use auto qos trust on the HQ side but does not use trust on the BR1 side. The DSG guide says the reason for not using the trust key word is because of the following: Note that we have not done any prior QOS classification/marking on the ESW module therefore we will use class-based marking (no use of the trust keyword when running auto qos). But the phones use the following markings by default. signaling (SCCP or SIP) - CoS 3 / cs3 media (RTP) - CoS 5 / DSCP 46 (EF) Why couldn't we just use the trust keyword on BR1 as well since the phone is already marking the packets correctly?
