Abstract:
BGP flow specification (RFC5575) describes the distribution policy
that contains filters and actions that apply when packets are
received on a router with the flow specification function turned on.
The popularity of these flow specification filters in deployment for
DoS and SDN/NFV has led to the requirement for more BGP flow
specification match filters in the NLRI and more BGP flow
specification actions. Two solutions exist for adding new filters:
1) expanding the BGP Flow Specification version 1 (NLRI match filters
and extended communities actions) to included limited number of
filters and actions, and 2) creating a BGP Flow Specification version
2 that allows for ordering filters and actions (using new NLRI and
wide-communities for actions). The two solutions can exist in
parallel.
This document contains an overview existing proposals for expansion
of BGP flow specification policy, proposals for BGP Flow
Specification v1 and a new BGP Flow specification version 2 that
supports order of filters and actions plus allowing more actions.
This document also provides rules for the interaction of IDR Flow
Specification policy (session ephemeral policy) with policy found in
I2RS (reboot ephemeral policy), and policy found in ACLs and Policy
routing (configuration policy). This document does not contain the
individual definitions of policy rule conditions or actions.
