Abstract
A network element configured to implement an Ethernet Virtual Private Network (EVPN) Virtual Private Wire Service (VPWS) Flexible Cross-Connect (FXC) local switching service includes a plurality of ports; and a switching fabric configured to switch traffic between the plurality of ports; wherein a set of ports is configured in a distributed Link Aggregation Group (LAG) with two nodes, and an inter-chassis link configured with a second network element, and wherein, responsive to a failure of the inter-chassis link, a distribution state of members in the distributed LAG is coordinated.

A network element configured to implement an Ethernet Virtual Private Network (EVPN) Virtual Private Wire Service (VPWS) local switching service, the network element comprising:
- a plurality of ports;
- and
- a switching fabric configured to switch traffic between the plurality of ports;
- wherein a set of ports is configured in a distributed Link Aggregation Group (LAG) with at least two nodes, and an inter-chassis link is configured with a second network element, and
- wherein, responsive to a failure of the inter-chassis link, a distribution state of members in the distributed LAG is coordinated utilizing a common VPWS that includes a plurality of members with different Ethernet Segment Instances (ESI) such that all of the plurality of members are configured with a same distribution state.
A method, implemented by a network element configured to implement an Ethernet Virtual Private Network (EVPN) Virtual Private Wire Service (VPWS) local switching service, the method comprising:
- operating a set of ports in a distributed Link Aggregation Group (LAG) with at least two nodes;
- operating an inter-chassis link with a second network element;
- and
- responsive to a failure of the inter-chassis link, coordinating a distribution state of members in the distributed LAG utilizing a common VPWS that includes a plurality of members with different Ethernet Segment Instances (ESI) such that all of the plurality of members are configured with a same distribution state.
A network configured to implement an Ethernet Virtual Private Network (EVPN) Virtual Private Wire Service (VPWS) local switching service, the network comprising:
- a first network element and a second network element each in a distributed Link Aggregation Group (LAG), and with an inter-chassis link between the first network element and the second network element,
- wherein, responsive to a failure of the inter-chassis link, a distribution state of members in the distributed LAG is coordinated utilizing a common VPWS that includes a plurality of members with different Ethernet Segment Instances (ESI) such that all of the plurality of members are configured with a same distribution state.
