Which default route you want to configure?

Static default or Dynamicly?

The ASPATH attribute is a well known transitive path attribute. So it can travel anywhere. For eg. from one AS to another and then to another AS and more. But the MED attribute can only travel to one AS to another but not more then that.

As a pass out student I will only say that its not about the institute that the student is forgetting something. Pls take in mind that if you are here for study then you have to keep revise all the things periodically to stay in touch with them. The teachers can try their best to help to get remind those, but its your responsibility to grab them thoroughly by doing revision.
