Options, or Padding fields, but it carries the Flow Label field. This facilitates IPv6 packet processing and improves processing efficiency. The Extension Header information field is added to the IPv6 packet header to support various options without changing the existing packet format, improving flexi...
The SRH header contains the following fields: · 8-bit Next Header—Identifies the type of the header next to the SRH. · 8-bit Hdr Ext Len—Length of the SRH header in 8-octet units, not including the first 8 octets. · 8-bit Routing Type—The value for this field is 4, which ...
The fields in the multicast address are: Flags Indicates flags set on the multicast address. The size of this field is 4 bits. As of RFC 3513, the only flag defined is the Transient (T) flag. The T flag uses the low-order bit of the Flags field. When set to 0, the T flag indi...
