- to send specifically requested link-state records
- to discover neighbors and build adjacencies between them
- to ensure database synchronization between routers
- to request specific link-state records from neighbor routers - to discover neighbors and build
adjacencies between them
2. Which OPSF packet contains the different types of link-state advertisements?
- hello
- DBD
- LSR
- LSU
- LSAck - LSU
Which three statements describe features of the OSPF topology table? (Choose three.)
- It is a link-state database that represents the network topology.
- Its contents are the result of running the SPF algorithm.
- When converged, all routers in an area have identical topology tables.
- The topology table contains feasible successor routes.
- The table can be viewed via the show ip ospf database command.
- After convergence, the table only contains the lowest cost route entries for all known networks. - - It is
a link-state database that represents the network topology.
- When converged, all routers in an area have identical topology tables.
- The table can be viewed via the show ip ospf database command.
What does an OSPF area contain?
, - routers that share the same router ID
- routers whose SPF trees are identical
- routers that have the same link-state information in their LSDBs
- routers that share the same process ID - routers that have the same link-state information in their
LSDBs
A router is participating in an OSPFv2 domain. What will always happen if the dead interval expires
before the router receives a hello packet from an adjacent DROTHER OSPF router?
- OSPF will run a new DR/BDR election.
- SPF will run and determine which neighbor router is "down".
- A new dead interval timer of 4 times the hello interval will start.
- OSPF will remove that neighbor from the router link-state database. - OSPF will remove that neighbor
from the router link-state database.
What is the order of packet types used by an OSPF router to establish convergence?
- The SPF algorithm chooses the best path based on 30-second updates.
- OSPF authentication is configured in the same way on IPv4 and IPv6 networks.
- It scales well in both small and large networks.
- Routers can be grouped into autonomous systems to support a hierarchical system. - It scales well in
both small and large networks.
What is used to create the OSPF neighbor table?
- adjacency database
- link-state database
