■ Backbone Router — a router that has at lease one directly
connected network in the backbone area. This includes all
ABRs. However, not all backbone routers must be ABRs. A
backbone router that has all its interfaces in the backbone
would be an internal backbone router.networks in their areas
and advertise them onto the backbone
■ Autonomous System Backbone Router (ASBR) —
router that has directly connected interfaces in non-OSPF
networks. These networks are then brought into an OSPF
domain. An ASBR is independent of the other router
classificiaitons.
* Note: The presence of Access Control Lists (ACLs) negatively
affects slow path routing.
