FAST CONVERGENCE FOR FAILURES OF LARGE SCALE VIRTUAL ETHERNET SEGMENTS IN EVPN AND PBB-EVPN

摘要

Systems, methods, and computer-readable media for fast convergence for virtual ethernet segments in EVPN and PBB-EVPN networks are disclosed. A first provider edge (PE) device can receive one or more advertising messages corresponding to one or more virtual ethernet segments, wherein each of the one or more advertising messages can include a port identifier. The first PE device maintains a table including the one or more virtual ethernet segments and the corresponding port identifier. The first PE device can receive a failure message from a second PE device that identifies a first port on the second PE device, and identifies, based on the table, at least one affected virtual ethernet segment that is associated with the first port. The first PE device can remove any routes that are associated with the at least one affected virtual ethernet segment and trigger mass designated-forwarding election for impacted virtual ethernet segments.

1. A method comprising:
receiving, at a first provider edge (PE) device, one or more advertising messages corresponding to one or more virtual ethernet segments, wherein each of the one or more advertising messages include a port identifier; maintaining, at the first PE device, a table including the one or more virtual ethernet segments and the corresponding port identifier; receiving, at the first PE device, a message from a second PE device that identifies a first port on the second PE device that has a failed status; identifying, based on the table, at least one affected virtual ethernet segment that is associated with the first port; and removing, at the first PE device, any routes associated with the at least one affected virtual ethernet segment.
