Last week I sent a below questions and asked the optimal place for an OSPF ABR (Area Border Router). There was a high level of participation. Thanks everyone who shared their thoughts. Hopefully they didn’t do it only for a free CCDE Workbook prize 🙂

 

CCDE WorkbookAnswer is Router G or H because

Between Router A and Router B there are 1800 different paths. (5×6)x2(5×6). If we would put all of them in a same area we would have flooding, convergence,resource utilization and troubleshooting problems.

If we turn one of the middle routers as an ABR, we will have only 32 paths max. (5×6) +2

I promised to share the CCDE Workbook for free with the first 5 correct answers and today I sent the book to the below winners.

In the CCDE Study book which I sent there is more detailed explanation of above question and many case studies.
