Active-Active Access to Transparent Interconnection of Lots of Links (TRILL) Edges

摘要

A routing bridge at an edge of a transparent interconnection of lots of links (TRILL) campus, comprises a first access port and a second access port each designated as one of a multi-chassis link aggregation (MC-LAG) designated forward (DF) port and an MC-LAG non-DF port, wherein the first access port is associated with a first pseudo-nickname, and a second access port is associated with a second pseudo-nickname, wherein a frame received via the first access port from a first customer equipment (CE) is replicated to generate a replicated frame, wherein the replicated frame is forwarded via the second access port to a second CE when the first pseudo-nickname and the second pseudo-nickname are the same, and when the first pseudo-nickname and the second pseudo-nickname are different and the second access port has been designated as the MC-LAG DF port.

1. A routing bridge at an edge of a transparent interconnection of lots of links (TRILL) campus, comprising:
a first access port designated as one of a multi-chassis link aggregation (MC-LAG) designated forward (DF) port and an MC-LAG non-DF port, wherein the first access port is associated with a first pseudo-nickname; and a second access port designated as one of the MC-LAG DF ports and MC-LAG non-DF ports, wherein the second access port is associated with a second pseudo-nickname, wherein a frame received via the first access port from a first customer equipment (CE) is replicated to generate a replicated frame, wherein the replicated frame is forwarded via the second access port to a second CE when the first pseudo-nickname and the second pseudo-nickname are the same, and when the first pseudo-nickname and the second pseudo-nickname are different and the second access port has been designated as the MC-LAG DF port, wherein the first pseudo-nickname and the second pseudo-nickname are the same when the first CE coupled to the first access port and the second CE coupled to the second access port are coupled to a same group of routing bridges, and wherein the first pseudo-nickname and the second pseudo-nickname are different when the first CE and the second CE are coupled to a different group of routing bridges.
