Hi gents, We have a design question of Flow Label. During the v6 transition, some DSL providers may want to create an IPv4-in-IPv6 tunnel from the BRAS to the AFTR to continue to provider v4 access over a v6 core network. To identify a CPE behind the BRAS, we propose to use the Flow Label. Each CPE will be assigned with a Flow Label. This Flow Label represents a flow of all encap v4-in-v6 traffic behind a CPE. The Flow Label will be applied on the v6 address of the BRAS. v6 hosts behind the CPE will have their v6 addresses and be most probably from a different v6 prefix, so their flow labels won't be affected.
You can find the details in: http://tools.ietf.org/html/draft-zhou-softwire-ds-lite-p2p-02 Our question is: "Is this usage compatible to RFC 3697?" We posted this question to Softwires and we were told to also ask 6man for input.
