- B. creation of LSPs across different IGP areas
- C. faster detection of LSP failure
- D. reduction in LSPs due to optimal path selection
Answer: A,C
NEW QUESTION 68
Exhibit.
You work for service provider B that wants to implement a hot potato routing policy on the network so that router C uses link C-A to reach service provider A's advertised routes and router D uses link D-B to reach Service Provider A's advertised routes Currently traffic from router C is traversing the core to exit the network on router B.
Referring to the exhibit, what are two design actions that would satisfy the requirements? (Choose two.)
