This draft defines a new flow-spec action, Redirect-to-Tunnel, and a new sub-TLV for Redirect-to-Tunnel extended community. A BGP UPDATE for a flow-spec NLRI can contain the extended community. When activated, the corresponding flow packets will be encapsulated and carried via a tunnel. The redirect tunnel information is encoded in BGP Path Attribute or extended community [TUNNELENCAPS][MPP] that is carried in the BGP flow-spec UPDATE. The draft expends the tunnel encapsulation attribute [TUNNELENCAPS] to apply to flow-spec SAFI, i.e., 133 and 134.
