Referring to the output in the exhibit, which statement is true?
A.
R2 is an ABR and will send a Type 7 LSA 0/0 route down into the nonbackbone area.
B.
R2 is an ABR and will send a Type 3 LSA 0/0 route down into the nonbackbone area.
C.
R2 will not send a Type 3 LSA 0/0 route into the nonbackbone area.
D.
R2 will add a metric cost of 10 to the existing metric of a 0/0 route it receives from the backbone
area and then send it into the nonbackbone area in a Type 5 LSA.

No-Summaries makes this a totally stubby area. no summaries.
no-summaries—(Optional)
If configured in combination with the default-metric statement, a totally stubby area only allows routes internal to the area and advertises the default route into the area.
By default, when the no-summaries statement is configured, a Type 3 LSA is injected into the nonbackbone area.
So “B” is right.
