Hello Rene/Laz,
I am going to use the below topology for my question.
In this diagram, OSPF is running everywhere. Router 3 and Router 4 have loopback addresses as it is depicted in the topology. My question is regarding path manipulation in OSPF. In this scenario, Router 4 is learning 3.3.3.3 route through two different ways. However, Router 4 is installing 3.3.3.3 route with the exit interface of G 0/2 as the best path (note: all the interfaces are Gig interface).
Question 1:
Is there any way to view the cost of the backup route for 3.3.3.3 in OSPF like it can be done in EIGRP topology table?
Now let’s say we want to manipulate the routing path. In this case, if we like to use G 0/1 as the primary path on Router 4, we can simply increase the cost on G 0/2 interface.
Question 2:
Now, when Router 3 will calculate the cost for 4.4.4.4 prefix, how would it do it?
Please break it down with an example if possible.
Thank you in advance
