Refer to the Exhibit.
The output in the exhibit was captured on an interface. Which three statements are true about the
configuration on the router with hostname SaoPaulo? (Choose three.)
A.
Wide metrics is not in use.
B.
The router has the overload bit set to “on”.
C.
Authentication is enabled.
D.
System ID is 1921.6805.2001.
E.
Level 2 routing is enabled.
Explanation:
E and C are correct. But i cant understand why “Wide metric is not use” here. I see TLV 22 and 135 in output. this mean that wide metric is in use.
“The Extended IS-Neighbors TLV (TLV 22) and the Extended IP Reachability TLV (TLV 135) are defined in “IS-IS extensions for Traffic Engineering””

Wide metrics is not in use because you have both “regular” and “wide-metrics” TLVs. When wide-metrics-only is enabled the “regular” TLV diseapear (128/130)
