In one embodiment, a method includes identifying, by a network component, a first segment identifier (SID) within a SID list. The first SID includes a first SID block and a first micro SID (uSID). The method also includes initializing, by the network component, a packing list of a uSID carrier with the first uSID of the first SID and initializing, by the network component, a packing block of the uSID carrier with the first SID block of the first SID. The method further includes initializing, by the network component, a remaining packing capacity of the packing list with a carrier capacity of the first SID and initializing, by the network component, an empty compressed SID list.

A node in a Segment Routing network includes circuitry configured to signal first service Segment Identifiers (SIDs), for one or more first Ethernet services configured at the node, to other nodes in the Segment Routing network, receive second service SIDs for one or more second Ethernet services configured at the other nodes in the Segment Routing network, and configure the second service SIDs for one or more second Ethernet services. The first service SIDs and the second service SIDs can be signaled by one of Interior Gateway Protocol (IGP) and Border Gateway Protocol (BGP).

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.
