OSPFv3 packets are encapsulated in IPv6 packets. Which of the following is the value of the Next Header field in the IPv6 packet header?
Options:
6
189
17
89
Comprehensive and Detailed In-Depth Explanation:
OSPFv3 (for IPv6) packets are directly encapsulated in IPv6 without using UDP or TCP.
The Next Header field in IPv6 is similar to the Protocol field in IPv4, indicating the protocol type of the payload.
IANA (Internet Assigned Numbers Authority) has assigned protocol number 89 to OSPF.
OSPFv3 packets always use Next Header value = 89 inside IPv6 headers.
