Play an AI-generated podcast conversation about this lesson

Which member is considered the highest priority member in the first output?

T_INET_2

T_MPLS

T_INET_1

T_INET_0 (correct)

What is the metric used in the best quality rule?

Outbandwidth (correct)

Inbandwidth

Moving up and down the list

Link-cost-threshold

What is the corrected available bandwidth difference (CBWD) in the first output?

999.9 kbps (correct)

899 kbps
