Topic:: Redistribution in OSPF / Redistribution between OSPF and EIGRP
I’m trying to check the difference between metric type 1 and metric type 2 configuration and it’s details in redistribution. I am unable to find details about it. Please direct me to check the appropriate topic if it is already in this site.

I asked recently the same here.

How to configure Redistribution between OSPF and RIP

The following lesson explains the various types of paths that OSPF shares, and the way that these are examined before looking at their metrics. These include External type 1 and External type 2 OSPF routes.

Now more info on the E1 and E2 routers and why they exist and how they are useful for redistribution can be found at the following post:

Redistribution between EIGRP and OSPF

Hello Sims I’m assuming you’re asking about External type 1 and 2 for OSPF, correct? You can find out more information about those at the following lesson: Now in a real-world scenario, when we redistribute, why would we choose E1 over E2 or E2 over E1? Well, first take a look at this post to remind us of how path cost is measured for E1 and E2: Now take a look at this diagram: [image] Imagine that all links are of the same type, and have the same cost. If you were to redistribute the…

I hope this has been helpful!
