OSPFv3 AS-External-LSAs advertise external IPv6 routing information across permitted OSPF areas.
The displayed LSA identifies the originating router as 10.0.3.3, confirming option C. The Route Tag field contains the value 1, confirming option B.
The LSA specifies Metric Type 2 with a metric of 1. For an E2 external route, the advertised external metric remains the primary route metric, while the internal cost to the ASBR can be used for tie-breaking. Therefore, option A describes the E2 metric behaviour.
Option D is not established by the exhibit. Although NSSA Type 7 LSAs can be translated into AS-External-LSAs by an ABR, the displayed Type 5 LSA does not independently demonstrate that translation occurred.
Consequently, the statements supported by the LSA are A, B, and C.
