4 | ## Combined Sequence Number |
||
5 | |||
6 | The sequence numbers for each LSA type are combined and synced as one 64-bit sequence number. |
||
7 | |||
8 | The Name LSA sequence number is represented by a 24-bit value. |
||
9 | |||
10 | The Adjacency LSA and Coordinate LSA sequence numbers are represented by 20-bit values. |
||
11 | |||
12 | The sequence numbers are combined as follows: |
||
13 | |||
14 | Combined sequence number = (Name LSA SeqNo << 40) | (Coordinate LSA SeqNo << 20) | (Adjacency LSA SeqNo) |
