Abstract:

A node in a Segment Routing network includes a plurality of ports and a switching fabric between the plurality of ports, wherein, for an Ethernet Tree (E-tree) service, a port is configured to transmit a packet with a plurality of Segment Identifiers (SID) including a first SID, a second SID, and a third SID, wherein the first SID identifies one of multicast, ingress replication for broadcast, and a destination node including any of a node SID and an anycast SID, wherein the second SID identifies a service including the E-tree service, and wherein the third SID identifies a source of the packet. A second port of the node is connected to a customer edge, and wherein the third SID is based on whether the customer edge is a leaf node or a root node in the E-tree service.
