LAB 3 task 4.9

My be my English bad and I not understand task.
Why all people use route-map with tag?
Why I cannot manipulate route on R5?
What about manipulate with distance under ospf process?

  • As long as you satisfy task requirments and do not break Don'ts of the lab, it doesnt matter which "tool" you will use to complete the task (route-map or distribute-list or any other solution). 

    D.

  • Yeah, you can use whatever tools or method for the task as long as it satisfy the requirements and the specifics of the lab.

    I personally like tagging because it seems to be easier for me to put up a mental picture of the traffic flow.  But what works for me may not works for you and vice versa.  You've to choose what works best for you.
