Ethernet VPN supports All-Active multihoming and an ingress Provider Edge (PE) can load balance traffic to all the egress PEs on a multihoming Ethernet Segment (MHES). Methods, devices, and systems to allow an operator to have the ingress PE load-balance to only a set of the PEs on the MHES are described. In the event that all PEs of the set are not usable (e.g., down, not attached to the ES, etc.), the ingress PE can load balance data traffic to one or more PEs on the MHES that are not in the set.

Aspects of the subject disclosure may include, for example, in response to a Border Gateway Protocol (BGP) update from an egress provider edge router connected to a destination customer network, receiving a request for an end-to-end SR policy or an end-to-end path from an ingress provider edge router, where the BGP update includes a prefix of the destination customer network and a first color; using color mapping data, determining a first domain associated with the first color and determining a second color to be associated with a second domain and mapped to the first color, where a color is a numerical value associated with a network intent of a domain, the color mapping data define mappings between different colors associated with different domains, and the mapped first color and second color enable identification of a first intent and a second intent that belong to the first domain and the second domain, respectively; and generating the end-to-end path reflecting each definition of the first and the second intents identified by the first color in the first domain and the second color in the second domain.

An improved mechanism is disclosed for advertising Segment Routing over IPv6 (SRv6)- based Border Gateway Protocol (BGP) services in networks supporting multiple Segment Identifier (SID) types (14). A Provider Edge (PE) router (100), acting as a BGP speaker (38), operates an SRv6-based BGP service and advertises it via BGP Update messages. These messages include Service SID information encoded as a Service SID Type- Length-Value (TLV) (12), and multiple Service SID Structure information (14), each corresponding to different SID types, such as uncompressed SIDs or micro SIDs (uSIDs). Upon receiving these messages, ingress PE routers select appropriate SID types based on capabilities or local policies, enhancing interoperability and reducing control-plane overhead. The solution uses a new Service SID TLV type (18) to indicate support for multiple SID structures, promoting efficient resource utilization and seamless multi¬ vendor deployment within SRv6 environments. This approach simplifies transitions between SID types and optimizes network scalability and flexibility.

A system and method are provided for faster convergence with multihoming using internet protocol (IP) performance measurement (PM) sessions to report, to a transmitting provider edge (PE), a state of health of a connection between a multihomed node and a receiving (PE). The state of health can be the liveness of the connection. The receiving PE locally monitors the state of health of its connection to the node, and encodes information of the state of health in a field of the PM session messages sent to the transmitting PE. For example, while the PM session messages indicate the connection is live, traffic from the transmitting PE to the node is routed through the receiving PE. Upon the PM session messages indicating the connection is no longer live, the transmitting PE instead routes traffic to the node through another receiving PE with which the node is multihomed.
