Detailed Description

This class represents (in the context of an EVPN instance) a local vRouter that's connected to a control node via XMPP. An EvpnLocalMcastNode gets created and associated as DBState with the broadcast MAC route advertised by the vRouter.

The EvpnLocalMcastNode mainly exists to translate the broadcast MAC route advertised by the vRouter into an EVPN Inclusive Multicast route. In the other direction, EvpnLocalMcastNode serves as the anchor point to build a vRouter specific ingress replication olist so that the vRouter can send multicast traffic to EVPN PEs (and possibly vRouters in test environment) that do not support edge replication.

An Inclusive Multicast route is added for each EvpnLocalMcastNode. The attributes of the Inclusive Multicast route are based on the broadcast MAC route corresponding to the EvpnLocalMcastNode. The label for the broadcast MAC route is advertised as the label for ingress replication in the PmsiTunnel attribute.

Constructor & Destructor Documentation

EvpnLocalMcastNode::EvpnLocalMcastNode	(	EvpnManagerPartition *	partition,
		EvpnRoute *	route
	)

Constructor for EvpnLocalMcastNode.

Add an Inclusive Multicast route corresponding to Broadcast MAC route.

Need to Notify the Broadcast MAC route so that the table Export method can run and build the OList. OList is not built till EvpnLocalMcastNode has been created.

void EvpnLocalMcastNode::TriggerUpdate ( )

virtual

Handle update of EvpnLocalMcastNode.

We delete and add the Inclusive Multicast route to ensure that all the attributes are updated. An in-place update is not always possible since the vRouter address is part of the key for the Inclusive Multicast route.

Implements EvpnMcastNode.
