LSAs

NLSR no longer uses a combined sequence number as 1523 has been merged.
It uses a separate sequence number for each type of LSA.

Combined Sequence Number

The sequence numbers for each LSA type are combined and synced as one 64-bit sequence number.

The Name LSA sequence number is represented by a 24-bit value.

The Adjacency LSA and Coordinate LSA sequence numbers are represented by 20-bit values.

The sequence numbers are combined as follows:

Combined sequence number = (Name LSA SeqNo << 40) | (Coordinate LSA SeqNo << 20) | (Adjacency LSA SeqNo)
