  B. 1
  C. 2
  D. 3

• Question 664:

  An operator configures an Alcatel-Lucent 7750 SR with a loopback interface and IPv6 address. The operator then configures a routing policy to redistribute the loopback prefix into OSPFv3. What type of LSA is used to advertise the route to other OSPFv3 routers in the same area?

  A. Router LSA
  B. AS External LSA
  C. Intra-Area Prefix LSA
  D. Inter-Area Prefix LSA
  E. Network LSA
  F. None of the statements are correct.
  B. AS External LSA

  A. The primary path will take R1-R3-R2-R4-R6. The secondary path will take R1-R3-R5-R6.
  B. The primary path will take R1-R3-R5-R4-R6. The secondary path will take R1-R3-R2-R4-R5-R6.
  C. The primary path will take R1-R3-R5-R6. The secondary path will take R1-R3-R2-R4-R5-R6.
  D. The primary path will take R1-R3-R5-R6. The secondary path will take R1-R3-R2-R4-R6.
