A router's Network LSA is shown in the figure. Which of the following statements is correct? display ospf Isdb network self-originate OSPFProcess1 with Router ID 10.0.12.2 Area: 0.0.0.0 Type: Network Lsid: 10.0.122 Advrtr: 10.0.12.2 Ls age: 824 Len: 32 Options : E \seq#:80000002 1 chksum : 0x8970 I Net mask: 255.255.255.0 IPriority : Low I Attached Router 10.0.12.2 . Attached Router 10.0.12.1

The command display ospf lsdb network self-originate shows the Type-2 Network LSAs originated by the local router.
- Router ID (B): The first line of the output, OSPFProcess1 with Router ID 10.0.12.2, explicitly states the Router ID of the device on which the command was executed.
- Network Segment (C): The Network LSA contains the Net mask: 255.255.255.0 (/24). The Link State ID (Lsid: 10.0.12.2) for a Network LSA is the IP address of the Designated Router's interface on that segment. Combining this IP address and mask confirms the network segment is 10.0.12.0/24.
- DR Role (D): Network LSAs (Type-2) are generated only by the Designated Router (DR) of a multi-access network. Since this router is originating the Network LSA (self-originate and Advrtr: 10.0.12.2), it must be the DR for this network segment.

A. The DR priority is an interface-specific parameter used for DR/BDR election and is not included in the Network LSA itself. The provided LSDB output does not contain this information.

1. Huawei HedEx Documentation (VRP V800R012C10), OSPF Command Reference, "display ospf lsdb". This document details the output fields of the command. It confirms that for a Network LSA, the Lsid is the DR's IP address, and the Advrtr is the DR's Router ID.

2. Huawei HCIP-Datacom-Advanced Routing & Switching Technology V1.0 Training Material, Chapter 2: OSPF Advanced Features. This courseware explains that Type-2 LSAs (Network LSAs) are generated by the DR to describe all routers on a multi-access network segment. The LSID is the DR's interface address.

3. RFC 2328 - OSPF Version 2, Section A.4.3 The Network-LSA. This standard specifies the contents of a Network LSA. It defines the Link State ID as the IP interface address of the network's Designated Router and confirms the LSA is advertised by the DR itself. It does not include a field for DR priority.
