Abstract:
This document describes the yang data model for packet forwarding
policy that filters received packets and forwards (or drops) the
packets. Prior to forwarding the packets out other interfaces, some
of the fields in the packets may be modified. If one considers the
packet reception an event, this packet policy is a minimalistic
Event-Match Condition-Action policy. This policy controls forwarding
of packets received by a routing device on one or more interfaces on
which this policy is enabled. The policy is composed of an ordered
list of policy rules. Each policy policy rule contains a set of
match conditions that filters for packets plus a set of actions to
modify the packet and forward packets. The match conditions can
match tuples in multiple layers (L1-L4, application), interface
received on, and and other conditions regarding the packet (size of
packet, time of day). The modify packet actions allow for setting
things within the packet plus decapsulation and encapsulation packet.
The forwarding actions include forwarding via interfaces, tunnels, or
nexthops and dropping the packet. The policy model can be used with
the session ephemeral (BGP Flow Specifications), reboot ephemeral
state (I2RS ephemeral), and non-ephemeral routing/forwarding state
(e.g. configuration state ).
