Abstract

An apparatus configured to provide active-active access to a transparent interconnection of lots of links (TRILL) campus. The apparatus includes a first access port associated with a first customer equipment (CE) and a second access port associated with a second CE. The first access port is configured to receive a frame from the first CE. The apparatus includes a processor configured to replicate the frame to generate a replicated frame, determine that a pseudo-nickname associated with the first access port and the pseudo-nickname associated with the second access port are the same, and determine that the first access port and the second access port are associated with different multi-chassis link aggregations (MC-LAGs). The apparatus also includes a transmitter configured to forward the replicated frame to the second CE using the second access port.

First claim

What is claimed is:

1. An apparatus configured to provide active-active access to a transparent interconnection of lots of links (TRILL) campus, comprising:
a first access port associated with a first customer equipment (CE) and a second access port associated with a second CE, the first access port configured to receive a frame from the first CE;
a processor coupled to the first access port and the second access port, the processor configured to:
replicate the frame to generate a replicated frame;
determine that a pseudo-nickname associated with the first access port and the pseudo-nickname associated with the second access port are the same; and
determine that the first access port and the second access port are associated with different multi-chassis link aggregations (MC-LAGs); and

a transmitter coupled to the processor, the transmitter configured to forward the replicated frame to the second CE using the second access port.

2. The apparatus of claim 1 , wherein the processor is configured to encapsulate the frame to generate an encapsulated frame.

3. The apparatus of claim 2 , wherein the processor is configured to associate the encapsulated frame with the pseudo-nickname.

4. The apparatus of claim 3 , wherein the transmitter is configured to multicast the encapsulated frame to the TRILL campus.

5. The apparatus of claim 1 , wherein the apparatus is a routing bridge or a router.

6. The apparatus of claim 1 , wherein the frame is a flooded broadcast, unicast, or multicast (BUM) data frame.

7. An apparatus configured to provide active-active access to a transparent interconnection of lots of links (TRILL) campus, comprising:
a first access port associated with a first customer equipment (CE) and a second access port associated with a second CE, the first access port configured to receive a frame from the first CE;
a processor coupled to the first access port and the second access port, the processor configured to:
replicate the frame to generate a replicated frame;
determine that a pseudo-nickname associated with the first access port and a pseudo-nickname associated with the second access port are different; and
determine that the second access port is a designated forwarding port; and

a transmitter coupled to the processor, the transmitter configured to forward the replicated frame to the second CE using the second access port.

8. The apparatus of claim 7 , wherein the processor is further configured to encapsulate the frame to generate an encapsulated frame.

9. The apparatus of claim 8 , wherein the encapsulated frame is associated with the pseudo-nickname associated with the first access port.

10. The apparatus of claim 9 , wherein the transmitter is further configured to multicast the encapsulated frame to the TRILL campus.

11. The apparatus of claim 7 , wherein the apparatus is a routing bridge or a router.

12. The apparatus of claim 7 , wherein the frame is a flooded broadcast, unicast, or multicast (BUM) data frame.
