Use holddown timers when topologies change to allow for convergence. D . Maintain multiple databases: neighbor, topology and routing.
In the topology shown, router R1 is an ASBR configured to export external routes to OSPF.Which of the following statements regarding the OSPF LSAs in the network is true? A . Router R1 generates a type 5 LSA that is flooded through all OSPF areas. B . Router R1 generates a type 7 LSA that is flooded through all OSPF areas. C . Router R1 generates a type 5 LSA that is flooded through area 1.Router R2 generates a type 7 LSA that is flooded through areas 0 and 2. D . Router R1 generates a type 7 LSA that is flooded through area 1.Router R3 generates a type 5 LSA that is flooded through areas 0 and 2.
What is the protocol number for OSPF in the IP header? A . OSPF uses TCP, so the protocol number is 6. B . OSPF uses UDP, so the protocol number is 17. C . OSPF does not use I E . OSPF has its own protocol number of 89.
Which of the following statements regarding OSPF routing updates on a point-to-point link is true? A . On a point-to-point link, there is no need for a DR and BDR election; all routing updates are sent to 18.104.22.168. B . On a point-to-point link, a DR and BDR are elected.The DR sends link-state advertisements describing the network. C . On a point-to-point link, a DR and BDR are elected.To ensure resiliency, both the DR and BDR send link-state advertisements describing the network. D . On a point-to-point link, there is no need for a DR and BDR election.All routing updates are sent to the unicast address of the neighbor’s interface.
Routers R1 „ R2, and R3 are running a classful routing protocol between them.Assuming that router R1 advertises all directly connected networks, how will these networks be represented in router R3’s routing table?
A . Router R3’s routing table can only contain one of the routes, which will result in route flapping. B . Router R3’s routing table will have one entry for 10.1.1.0/24 and one entry for 10.1.2.0/24. C . The networks will be represented with one entry of 10.0.0.0/8 in router R3’s routing table. D . The networks will be represented with one entry of 10.0.0.0/24 in router R3’s route table.
Which of the following best describes the type of packets used by OSPF routers to exchange updates on a point-to-point link? A . IP packets sent to an IP multicast address. B . TCP packets sent to an IP multicast address. C . IP packets sent to an IP unicast address. D . UDP packets sent to an IP multicast address.
