Examples of this protocol include RIP
- C.
This protocol determines the direction (vector) and distance (hop count) to any network in the internetwork
- D.
A router needs to know the entire path to every network segment
- E.
This process is also known as "routing by rumor"
- F.
Routers that are running the distance vector routing protocol send periodic updates only when there are changes in the network

- A.
The link-state database is used to calculate the paths with the highest bandwidths on the network
- B.
Link-State routing protocols respond quickly to network changes
- C.
In link-state routing protocols, each router periodically sends messages to the network, listing the routers to which it is directly connected and also information about whether the link to each router is active
- D.
LS routing protocols send periodic updates (LS refreshes) at long time intervals, approx once every 30 mins
- E.
In LS routing protocols, every router tries to build it's own internal map of the network topology
- F.
LS routing protocols send periodic detailed routing tables eeven tho network changes have occurred
