Hey guys, I wanted to clear up a few things regarding the blog and some of the questions. We have TWO type-7 NSSA LSAs coming into R5 originally: One with forwarding-address 6.6.6.6 and the other 65.65.65.6. The question is how do we select which one to set in the type-5 LSA ? In the blog I believe I incorrectly stated it was simply due to the lowest IP address. Some of you called me on that saying you saw it was the highest ip address in your experiments and I believe you are correct.
The reason I was seeing the lowest IP address was because the metric from R5 to the ASBR (R6) in my setup was always tilted. The link to 56.56.56.6 started with a metric of 1 whereas the link to 65.65.65.6 started with a metric of 10. THAT is the reason the 6.6.6.6 was chosen. If the metric to the ASBR was indeed equal, I believe we would see the reverse. Thanks for all the interest and EXCELLENT questions. Sorry if I confused anybody, I think it was about 5:00 AM and I was running about 70 hours that week and running a class :P Keep studying hard!!! P.S.
