I'm don't really buy the extra config argument. It's literally
differences measured in seconds or minutes between the configuration
effort, and in the context of the operational benefits over time of link
state verses distance vector, I think they're worth spending.
However, if you want a really simple OSPF config, the following two
lines will make OSPF just work everywhere it can on a Cisco router
router ospf 64512
network 0.0.0.0 255.255.255.255 area 0
One of the large delays you see in OSPF is election of the designated
router on multi-access links such as ethernets. As ethernet is being
very commonly used for point-to-point non-edge links, you can eliminate
that delay and also the corresponding network LSA by making OSPF treat
the link as a point-to-point link e.g.
ip ospf network point-to-point
If your implementation doesn't support point-to-point mode for an
interface, point-to-multipoint mode on an ethernet would achieve
something somewhat equivalent.
