A source node in a first domain in a multi-domain network includes a plurality of ports; and switching circuitry configured to forward packets between the plurality of ports, wherein the source node is configured to, for a packet destined for a destination node in another domain in the multi-domain network, add a list of Segment Identifiers (SIDs) to the packet for loose source-based routing from the source node, through the first domain, and to the another domain, and forward the packet via a port of the plurality of ports and with the list of SIDs, wherein the list of SIDs includes at least one SID representing both an anycast SID and a binding SID. The SID is associated with an anycast group that includes a plurality of nodes, and with a binding segment in the second domain, the binding segment includes a different SID list for each node of the plurality of nodes.
