The LS Type field in OSPFv3 LSAs has been increased from 8 bits to 16 bits. What is a purpose of two of the high-order bits in this extended field?
- to denote the flooding scope of the LSA
- to carry the ABR RID
- to indicate the address family (IPv4 or IPv6)
- to hold the OSPFv3 area ID
Explanation: The three high-order bits of the new LS Type field allow for the encoding of flood information. The first bit indicates how a router should handle an LSA if it is unrecognized. The second and third bits indicate how the LSA should be flooded.
