Hello Shishio-san,

Would the below text already present in the second draft not address your
question ?

Quote:

Another traffic filtering action defined in [RFC5575] as a BGP extended
community is redirect.  To allow an IPv6 address specific route-target, a
new traffic action IPv6 address specific extended community is provided.
The extended community type has the value  0x800b.

Redirect-IPv6: The redirect IPv6 address specific extended community allows
the traffic to be redirected to a VRF routing instance that lists the
specified IPv6 address specific route-target in its import policy.  If
several local instances match this criteria, the choice between them is a
local matter (for example, the instance with the lowest Route Distinguisher
value can be elected).  This extended community uses the same encoding as
the IPv6 address specific Route Target extended community [RFC5701].

Ref section 4 of: https://tools.ietf.org/html/draft-ietf-idr-flow-spec-v6-06

Many thx,
Robert.
