Which of the following is an advantage of enabling label stack reduction for a CSPF-calculated path, as compared to using plain CSPF?
Which of the following is an advantage of enabling label stack reduction for a CSPF-calculated path, as compared to using plain CSPF?
Enabling label stack reduction for a CSPF-calculated path primarily reduces the number of labels that need to be included in the label stack. This is achieved by summarizing segments into fewer labels, which effectively reduces the number of hops represented in the end-to-end path. This simplification helps optimize the use of resources and can improve performance in label switching routers.
D is the correct answer
D is correct. In addition to the label reduction benefit, using Node SIDs wherever possible increase the use of ECMP.
