BGP-LS
1. BGP Link-State Extension for Distribution of IP Tunnel Information
Publication: IETF Individual Draft
Publication History: 2016-03
Publication URL: https://tools.ietf.org/html/draft-dong-idr-ls-ip-tunnel-00
Description:
This document specifies extensions to BGP-LS for the collection and distribution of IP tunnel information. Such information can be distributed to external components for service mapping and tunnel selection.
BGP Flowspec
1. BGP Flow-Spec Redirect to Tunnel action
Publication: IETF Individual Draft
Publication History: 2015-10
Publication URL: https://tools.ietf.org/html/draft-hao-idr-flowspec-redirect-tunnel-00
Description:
This draft defines a new flow-spec action, redirect-to-Tunnel, and a new sub-TLV for the redirect extended community to provide redirecting a flow to a tunnel. A BGP UPDATE for a flow-spec NLRI can contain the extended community. When activated, the corresponding flow packets will be encapsulated by a tunnel encapsulation protocol and then be forward to the target IP address. The redirected tunnel information and target IP address are encoded in BGP Path Attribute [TUNNELENCAPS] [MPP] that is carried in the BGP flow-spec UPDATE. The draft expends the tunnel encapsulation attribute to apply to flow-spec SAFI, i.e. 133 and 134.
2. BGP FlowSpec Redirect to Generalized Segment ID Action
Publication: IETF Individual Draft
Publication History: 2016-03
Publication URL: https://tools.ietf.org/html/draft-li-idr-flowspec-redirect-generalized-sid-00
Description:
This document defines a new type of the redirect extended community, called as Redirect to Generalized Segment ID Extended Community. When activated, the Redirect to Generalized Segment ID Extended Community is used by BGP FlowSpec Controller to signal the specific redirecting action to BGP Flowspec Client, and then the BGP Flowspec Client will use the Generalized Segment ID and the Segment Type to find a local forwarding entity in a local mapping table.
3. Flowspec Indirection-id Redirect
Publication: IETF WG Draft
Publication History: 2016-08
Publication URL: https://tools.ietf.org/html/draft-ietf-idr-flowspec-path-redirect-00
Description:
Flowspec is an extension to BGP that allows for the dissemination of traffic flow specification rules. This has many possible applications but the primary one for many network operators is the distribution of traffic filtering actions for DDoS mitigation. The flow-spec standard RFC5575 [2] defines a redirect-to-VRF action for policy-based forwarding but this mechanism is not always sufficient, particularly if the redirected traffic needs to be steered into an engineered path or into a service plane. This document defines a new extended community known as redirect-to- indirection-id (32-bit) flowspec action to provide advanced redirection capabilities on flowspec clients. When activated, the flowspec extended community is used by a flowspec client to find the correct next-hop entry within a localised indirection-id mapping table. The functionality present in this draft allows a network controller to decouple flowspec functionality from the creation and maintainance of the network’s service plane itself including the setup of tunnels and other service constructs that could be managed by other network devices.
4. Dissemination of Flow Specification Rules for NVO3
Publication: IETF WG Draft
Publication History: 2016-03
Publication URL: https://tools.ietf.org/html/draft-ietf-idr-flowspec-nvo3-00
Description:
This draft proposes a new subset of component types to support the NVO3 flow-spec application.
BGP RPD
1. BGP Extensions for Routing Policy Distribution (RPD)
Publication: IETF WG Draft
Publication History: 2019-11
Publication URL: https://tools.ietf.org/html/draft-ietf-idr-rpd-00
Description:
It is hard to adjust traffic and optimize traffic paths on a traditional IP network from time to time through manual configurations. It is desirable to have an automatic mechanism for setting up routing policies, which adjust traffic and optimize traffic paths automatically. This document describes BGP Extensions for Routing Policy Distribution (BGP RPD) to support this.
BGP SBFD
1. BGP Link-State Extensions for Seamless BFD
Publication: IETF WG Draft
Publication History: 2019-03
Publication URL: https://tools.ietf.org/html/draft-ietf-idr-bgp-ls-sbfd-extensions-00
Description:
Seamless Bidirectional Forwarding Detection (S-BFD) defines a simplified mechanism to use Bidirectional Forwarding Detection (BFD) with large portions of negotiation aspects eliminated, thus providing benefits such as quick provisioning as well as improved control and flexibility to network nodes initiating the path monitoring. The link-state routing protocols (IS-IS and OSPF) have been extended to advertise the Seamless BFD (S-BFD) Discriminators. This draft defines extensions to the BGP Link-state address-family to carry the S-BFD Discriminators information via BGP.
