Status of this Memo @@ -111,32 +111,32 @@ auto-discovery [6074]. This draft proposes a new subset of component types and extended community to support L2VPN flow-spec application. The flow-spec rules can be enforced on all border routers or on some interface sets of the border routers. SAFI=134 in [RFC5575] is redefined for dissemination traffic filtering information in an L2VPN environment. 2. Layer 2 Flow Specification encoding in BGP - The [RFC5575] defines SAFI 133 and SAFI 134 for ''dissemination of - IPv4 flow specification rules'' and ''dissemination of VPNv4 flow - specification rules'' respectively. [draft-ietf-idr-flow-spec-v6-06] + The [RFC5575] defines SAFI 133 and SAFI 134 for "dissemination of + IPv4 flow specification rules" and "dissemination of VPNv4 flow + specification rules" respectively. [draft-ietf-idr-flow-spec-v6-06] redefines the [RFC5575] SAFIs in order to make them applicable to both IPv4 and IPv6 applications. This document will further redefine the SAFI 134 in order to make them applicable to L2VPN applications. The following changes are defined: - ''SAFI 134 for dissemination of L3VPN flow specification rules'' to - now be defined as ''SAFI 134 for dissemination of VPN flow - specification rules'' + "SAFI 134 for dissemination of L3VPN flow specification rules" to + now be defined as "SAFI 134 for dissemination of VPN flow + specification rules" For SAFI 134 the indication to which address family it is referring to will be recognized by AFI value (AFI=1 for VPNv4, AFI=2 VPNv6 and AFI=25 for L2VPN). Such modification is fully backwards compatible with existing implementation and production deployments. 3. Ethernet Flow Specification encoding in BGP The NLRI format for this address family consists of a fixed-length Route Distinguisher field (8 bytes) followed by a flow specification,
