(10 cards)
What is an area?
A set of routers and links that share the same LSDB.
What is the backbone area (area 0)?
An area that all other areas must connect to.
What are internal routers?
Routers with all interfaces in the same area.
What are Area Border Routers (ABRs)?
Routers with interfaces in multiple areas.
What are backbone routers?
Routers connected to the backbone area (area 0)
What is an intra-area route?
A route to a destination inside the same OSPF area.
What is an interarea route?
A route to a destination in a different OSPF area.
What is reference-bandwidth?
The reference bandwidth is a setting in routers that help to influence the cost that determines the SPF. It does not represent the link speed. Formula is cost = reference bandwidth / interface bandwidth.
What is interface-bandwidth?
Interface bandwidth is a setting that can influence SPF cost, but it’s not recommended to change. A good practice is to leave this value as default to match link speed automatically.
What is maximum-paths?
Maximum paths refers to the maximum amount of paths a router can use to load balance data.
