Need understanding on Wireshark Capture from LSA update of a link.PCAP attached

Question

Consider OSPF in Area 0 is running on all routers and interfaces.
I advertise a route 223.0.0.1/24 from R4 in the diagram. PCAP i shared is between r2 and r1 where R2 sends "LS Update"
I'm unable to understand the Contents of LSA Type 1 which has 5 links.
Please help me to understand why 40.0.0.0 is in that LSA update although it is being advertised earlier and there was convergence before the advertisment of 223.0.0.1 link?

and what are the Other links for in that Update

Here is a Topology given Below And PCAP is also given Below from Wire shark

Answer 1

For each interface state change a new Router-LSA is created containing the collected states of the router's interfaces.

According to RFC2328:

section 4.4

  1      Router-LSAs        Originated by all routers.
                              This LSA describes
                              the collected states of the
                              router's interfaces to an
                              area. Flooded throughout a
                              single area only.

section 12.4

    (2) An interface's state changes (see Section 9.1).  This may
        mean that it is necessary to produce a new instance of the
        router-LSA.
