Abstract:
In one embodiment, a method includes, subsequent to receipt of a packet 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, the provider network node forming 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 packet to the second customer network node via the local connection instead of via the EVPN-VPWS domain; and if the local connection is determined to have failed, switching the packet to the second customer network node via the EVPN-VPWS domain.
