From cfc7a107e6cb8be6e7c53a08e23a146c431c8e90 Mon Sep 17 00:00:00 2001 From: Benoît Ganne Date: Wed, 26 Jun 2019 13:36:51 +0200 Subject: gbp: add anonymous l3-out external interfaces MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit So far, GBP l3-out packets classification & policy relied on programmed EP. All traffic to/from l3-out must go through a known EP. This patch introduces a new feature where l3-out next-hops are only known by their subnets (l3-out prefixes). As there are no longer known EPs to program, an interface must be configured as external anonymous l3-out. Packets classification & policy on this interface will rely on the external subnets programmed in the BD VRF. Note that contrary to all other interfaces in a GBP BD, external anonymous l3-out interfaces have BD L2 learning turned on and rely on ARP/ND.
