gbp: add anonymous l3-out external interfaces
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. Type: feature Change-Id: Ieedb29dff4e967d08c4301e82d06bff450a63e5f Signed-off-by: Benoît Ganne <bganne@cisco.com>
