80 * 2. Each local ES-EVI entry is sent to BGP which advertises it as an
81 * EAD-EVI (Type-1 EVPN) route
82 * 3. Local ES-EVI setup is re-evaluated on the following triggers -
83 * a. When an ESI is set or cleared on an access port.
84 * b. When an access port associated with an ESI is deleted.
85 * c. When VLAN member ship changes on an access port.
86 * d. When a VXLAN_IF is set or cleared on an access broadcast domain.
87 * e. When a L2-VNI is added or deleted for a VxLAN_IF.
88 * 4. Currently zebra doesn't remote ES-EVIs. Those are managed and maintained
89 * entirely in BGP which consolidates them into a remote ES. The remote ES
90 * is then sent to zebra which allocates a NHG for it.
