QUESTION (from a student): Why OSPF E1 routes are preferred over E2 type? ANSWER: As I have explained in the video lecture, E1 routes = External cost + Internal cost to ASBR E2 routes = External cost Therefore, E1 has more cost(metric) to the same destination as compared to E2 .. ... & as we know that a route with highest Metric is always preferred over others if AD is same. Because it causes the packets to reach to destination more fast. Therefore OSPF has been designed so that it prefers E1 routes over E2 routes. (Same is true for N1/N2 routes with NSSA type areas in OSPF). I hope it clarifies your concept now, I have tried as simple English language as possible.

@kathir6748 Год назад

Great Explanation sir.... I have one doubt . In your topology,If we configure NsSa, there will be two types of LSA 4 present in other areas right? Or if not, LSA 4 will advertise about which ASBR link ?

@waqasulkarim 9 месяцев назад

Right, there will be two

Why N1 route is preferred over N2 route in ospf and E1 over E2 ??

Hi @Manish, ANSWER: As I have explained in the video lecture, E1 routes = External cost + Internal cost to ASBR E2 routes = External cost Therefore, E1 has more cost(metric) to the same destination as compared to E2 .. ... & as we know that a route with highest Metric is always preferred over others if AD is same.

@Mac_03 2 года назад

@@waqasulkarim I believe route with lowest metric will preferred if AD same. Longest prefix length AD Lowest Metric
