Overview
- Link-state, uses Dijkstra algorithm
Router Types
- Level 1: intra-area (can only form relationships with other Level 1 routers).
- Level 2: inter-area (can only form relationships with other Level 2 routers).
- Level 1-2: both.
Routing
- Level 1 ↔ Level 1
- Level 2 ↔ Level 2
- Level 1 ↔ Level 1-2 ↔ Level 2
Other Stuff
- Area borders are between routers (i.e. on the link):
- in contrast to OSPF where the area border is within an ABR.
