Techniques for preferred path local switching in EVPN-VPWS

One or more non-transitory tangible media that includes code for execution and when executed by a processor is operable to perform operations comprising:

• subsequent to receipt of a plurality of packets from a first customer network node destined for a second customer network node at a first provider network node, determining whether a local connection exists between the first provider network node and the second customer network node based on determining whether there are multiple connections to a same service instance identifier via different Ethernet segment identifiers at the first provider network node, wherein the first provider network node comprises part of an Ethernet Virtual Private Network (“EVPN”) —Virtual Private Wire Service (“VPWS”) domain;
• if a local connection is determined to exist between the first provider network node and the second customer network node, determining whether the local connection has failed;
• if the local connection is determined not to have failed, switching the plurality of packets to the second customer network node to provide preferred path local switching via the local connection instead of via the EVPN-VPWS domain;
• and
• if the local connection is determined to have failed, switching the plurality of packets to the second customer network node via the EVPN-VPWS domain.

An apparatus comprising:

• a memory element configured to store data;
• and
• a processor operable to execute instructions associated with the data, wherein executing the instructions causes the apparatus to perform operations, comprising:
• subsequent to receipt of a plurality of packets from a first customer network node destined for a second customer network node at a first provider network node, determining whether a local connection exists between the first provider network node and the second customer network node based on determining whether there are multiple connections to a same service instance identifier via different Ethernet segment identifiers at the first provider network node, wherein the first provider network node comprises part of an Ethernet Virtual Private Network (“EVPN”)—Virtual Private Wire Service (“VPWS”) domain;
• if a local connection is determined to exist between the first provider network node and the second customer network node, determining whether the local connection has failed;
• if the local connection is determined not to have failed, switching the plurality of packets to the second customer network node to provide preferred path local switching via the local connection instead of via the EVPN-VPWS domain;
• and
• if the local connection is determined to have failed, switching the plurality of packets to the second customer network node via the EVPN-VPWS domain.
