A company is considering TRILL and SPBM as options for the data center architecture. The company is interested in how the solution handles load-balancing unicast traffic. What correctly describes…
The correct answer is B. SPBM can use Equal Cost Multi-Path (ECMP). TRILL does not support ECMP for unicasts, but can load-balance multicast, depending on the tree configuration. See the full explanation below for the reasoning.
Question
A company is considering TRILL and SPBM as options for the data center architecture. The company is interested in how the solution handles load-balancing unicast traffic. What correctly describes the TRILL and SPBM options?
Options
- ATRILL can use Equal Cost Multi-Path (ECMP). SPBM selects one best path to each SPBM switch in each B-VLAN, but can select different paths for different B-VLANs
- BSPBM can use Equal Cost Multi-Path (ECMP). TRILL does not support ECMP for unicasts, but can load-balance multicast, depending on the tree configuration.
- CNeither SPBM nor TRILL can use Equal Cost Multi-Path (ECMP). Both technologies can send traffic for different VLAN VLANs or I-SIDs on different links.
- DBoth SPBM and TRILL can use Equal Cost Multi-Path (ECMP) to load-balance unicasts, provided that ECMP is enable at hardware level.
