OK, I have run a couple of Q&a
Howard, Chuck et al,
Even more strange is if you configure the loopback interface
as a point-to-point network -
e.g.
int lo0
ip address 172.16.1.1 255.255.255.0
ip osdpf network-type point-to-point
router ospf 10
network 172.16.1.1 0.0.0.0 area 0
In this configuration, the OSPF process wo

Unless there have been recent IOS changes (I'm really most current in

Use loopback ports in OSPF so you can set the Router OSPF ID, otherwise it
will take the highest IP address.

Well yes, you are correct. I guess I (or Dr. Garcia-Luna-

There is no need for split horizon with a link state protocol.
What is the command.

It's not easy to compare EIGRP and OSPF. Since OSPF is a link-state
protocol, it advertises links and their states, not routes. OSPF is quiet
(except for neighbor
OK, let me say it this way: EIGRP is not a distance vector and link-state
protocol. It is an advanced distance-vector protocol. It may share some
features with link-state protocols, such as fast convergence, but it does
not behave like a link-state protocol.

EIGRP is not a link-state protocol. It's an "advanced" distance-vector
protocol.
Regarding the main question, I wouldn't think OSPF would need to deal with

Here's a little note on split horizon, it appears to be rip ane igrp/eigrp

Hi,
If I remember correctly, split horizon is needed (and applicable) only on
distance vector (RIP, (E)IGRP).. link state
