OSPF is a link-state routing protocol。It is designed to be run internal to a single __（71__system。Each OSPF router maintains an identical __（72）__ describing the autonomous system’s topology。From this database，a routing table is calculated by constructing a shortest-path __（73）__。OSPF recalculates routes quickly in the face of topological changes，utilizing a minimum of routing __（74）__ traffic。OSPF provides support for equal-cost multipath。An area routing capability is provided，enabling an additional level of routing protection and a reduction in routing protocol __（75）__。A.autonomousB.networkC.computerD.server

What two things will a router do when running a distance vector routing protocol?()
A. Send periodic updates regardless of topology changes.B. Send entire routing table to all routers in the routing domain.C. Use the shortest-path algorithm to the determine best path.D.

考题
One of the most widely used routing protocols in IP networks is the Routing Information Protocol（RIP）。RIP is the canonical example of a routing protocol built on the（ ）algorithm.Routing protocols in internetworks differ slightly from the idealized graph model.In an internetwork,the goal of the routers to forward packets to various（请作答此空）.
Routers running RIP send their advertisement about cost every（ ）seconds.A router also sends an update message whenever an update from another router causes it to change its routing table.
It is possible to use a range of different metrics or costs for the links in a routing protocol.RIP takes the simplest approach,with all link costs being equal（ ）。Thus it always tries to find the minimum hop route.Valid distances are 1 through（ ）。This also limits RIP to running on fairly small networks.A.computers
B.routers
C.switches
D.networks
