Comprehensive and Detailed In-Depth Explanation:

1. Understanding OSPFv3 and DR/BDR Election

In OSPFv3, on broadcast and non-broadcast networks, routers elect a Designated Router (DR) and a Backup Designated Router (BDR) to reduce LSA flooding.

The DR is responsible for generating Network LSAs (Type 2 LSAs) for the subnet.

The BDR takes over if the DR fails.

Other routers (DROther) only form adjacencies with the DR and BDR but still receive LSAs.

2. Understanding the LSA Output in the Figure

The LSA shown in the figure is a Type 1 (Router LSA).

The originating router is R2 (Router ID: 10.0.2.2).

The LSA lists two " Transit Network " links connected to R2.

The Neighbor Router IDs listed are 10.0.1.1 (R1) and 10.0.2.2 (R2).

3. Why the Statement is FALSE

A transit network (broadcast network) should have only ONE DR.

R1 and R2 both being DRs is incorrect, as only one DR per subnet should exist.

The presence of two " Transit Network " entries in the LSA suggests that there are two separate OSPF broadcast networks, each with its own DR.

This means R1 and R2 are each DRs on separate networks, but not both DRs on the same network.

Final Answer:

Answer: B (FALSE)
