1.10 Troubleshoot OSPF (v2/v3)
1.10.a Address families (IPv4, IPv6)
1.10.b Neighbor relationship and authentication
1.10.c Network types, area types, and router types
1.10.c Point-to-point, multipoint, broadcast, nonbroadcast
1.10.c (ii) Area type: backbone, normal, transit, stub, NSSA, totally stub
1.10.c (iii) Internal router, backbone router, ABR, ASBR
1.10.c (iv) Virtual link
1.10.d Path preference
Backbone area
An OSPF backbone area consists of all networks in area ID 0.0. 0.0, their attached routing devices, and all ABRs. The backbone itself does not have any ABRs. The backbone distributes routing information between areas.
Area border router (ABR)
A router that connects one or more areas to the OSPF backbone.
Autonomous system border router (ASBR)
A router is connected to one or more logical entities (AS), usually through an exterior routing protocol such as BGP.
Virtual link
Virtual links are used to extend Area 0 across another area. They also can be thought of as tunnels for LSAs. They are deployed in cases when areas become partitioned or an area does not border Area 0.
