WebThe default is still L3 which covers source and destination addresses along with flow label and IPv6 protocol. A separate sysctl is added for IPv6, allowing IPv4 and IPv6 to use different algorithms if desired. The first 2 patches modify the IPv4 variant so that at the end of the patch set the ipv4 and ipv6 implementations are direct parallels. WebFor example, when a router receives a packet from a particular source with an unknown, non-zero flow label, a router can process its IPv6 header. The router processes any necessary extension headers in the same way that the router processes extension headers with the flow label field set to zero. The routers also determine the next-hop interface.
WebDec 20, 2024 · The Flow Label field in the IPv6 header is used by a source to label sequences of packets to be treated in the network as a single flow and, as reported in [RFC6438], it can be used for load balancing (LB) and equal-cost multipath (ECMP).
