zebra: Ethernet segment management and support for MAC-ECMP
1. Local ethernet segments are configured in zebra by attaching a
local-es-id and sys-mac to a access interface -
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
!
interface hostbond1
evpn mh es-id 1
evpn mh es-sys-mac 00:00:00:00:01:11
!
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
This info is then sent to BGP and used for the generation of EAD-per-ES
routes.
2. Access VLANs associated with an (ES) access port are translated into
ES-EVI objects and sent to BGP. This is used by BGP for the
generation of EAD-EVI routes.
3. Remote ESs are imported by BGP and sent to zebra. A list of VTEPs
is maintained per-remote ES in zebra. This list is used for the creation
of the L2-NHG that is used for forwarding traffic.
4. MAC entries with a non-zero ESI destination use the L2-NHG associated
with the ESI for forwarding traffic over the VxLAN overlay.
Please see zebra_evpn_mh.h for the datastruct organization details.
