Which two items should you know when configuring OSPF to dynamically learn routes? ()(Choose two.)
A. OSPF area IDB. OSPF neighbor addressC. OSPF loopback addressD. OSPF authentication type
考题
Which of the following LSA types describe information related to topology or subnets useful for calculating routes for subnets inside the OSPF domain?()
A. 1B. 2C. 3D. 4E. 5F. 7
考题
Which three statements are correct about the differences in IS － IS and OSPF?()
A. IS - IS is more CPU - intensive than is OSPFB. For greater fine tuning there are more IS - IS timersC. IS - IS LSP con tains TLV fields and OSPF LSU contains the LSAsD. New additions to the protocol are easily implemented in OSPF but not with IS - ISE. OSPF has more area types than does IS - IS
