Detailed Description

This class represents a remote EVPN segment that has 2 or more PEs that are multi-homed to it. An EvpnSegment is created when we see a MAC route with a non-NULL ESI or when we see an AD route for the ESI in question.

An EvpnSegment contains a vector of lists of MAC routes that are dependent on it. There's a list entry in the vector for each DB partition. All the MAC routes in a given partition that are associated with the EvpnSegment are in inserted in the list for that partition. The lists are updated as and when the EvpnSegment for MAC routes is updated.

An EvpnSegment contains a list of Remote PEs that have advertised per-ESI AD routes for the EVPN segment in question. The list is updated when paths are added/deleted from the AD route. A change in the contents of the list triggers an update of all dependent MAC routes, so that their aliased paths can be updated. The single-active state of the EvpnSegment is also updated when the PE list is updated. The PE list is updated from the context of the bgp::EvpnSegment task.
