  • the router ID of the neighboring routers.
  • the OSPF state of each interface.
  • the IP address of the neighbor router interface to which this router is directly connected.

What does the show ip OSPF neighbor command Reveal?

The show ip ospf neighbor command can be used to find information about any OSPF neighborships, including the interface, the state, the neighbor’s address, and the neighbor’s router ID. To select a router ID for OSPF, a router goes through a process. When a router ID has been found, the process stops.

Which command displays OSPF routes?

To display general information about Open Shortest Path First (OSPF) routing instances, use the show ip ospf command. Use the show ip ospf command to display information about one or more OSPF instances.

Which three statements describe the similarities between OSPFv2 and OSPFv3 choose three group of answer choices?

Which three statements describe the similarities between OSPFv2 and OSPFv3? They both are link-state protocols, They both share the concept of multiple areas and They both use the same DR/BDR election process. A network administrator enters the command ipv6 router ospf 64 in global configuration mode.

How do I know if my OSPF neighbor is down?

You can use the show ip ospf neighbor command in order to determine the state of the OSPF neighbor or neighbors. The output of this command will most likely reveal one of these: nothing at all. state = down.

Do OSPF neighbors have to be directly connected?

OSPF is another inter-AS dynamic routing protocol. Since an autonomous system is formed by a connected set of routers it is true that routers that participate in EIGRP or OSPF are always connected. Neighbors are the routers that are directly accessible through directly connected interfaces.

What needs to match for OSPF neighbors?

OSPF Neighborship Requirements The devices must be in the same area. The devices must have the same authentication configuration. The devices must be on the same subnet. The devices hello and dead intervals must match.

What is the IP protocol number for OSPF packets?

OSPF Packets OSPF messages ride directly inside of IP packets as IP protocol number 89.

How do I enable ospf?

To enable OSPF on a Cisco router and advertise interfaces, the following tasks are required:

  1. Use the command router ospf process ID to start OSPF.
  2. Use the network command to enable the interfaces.
  3. Identify area assignments.
  4. (Optional) Assign the router ID.

How do I find my LSA type in ospf?

Verification. By using the show ip ospf database we can look at the LSDB and we can see the type 1 router LSAs, type 2 network LSAs and the type 3 summary LSAs here.

What is router ospf command?

Router (config)# router ospf process ID This command will enable OSPF routing protocol in router. Process ID is a positive integer. We can use any number from 1 to 65,535. Process ID is locally significant. We can run multiple OSPF process on same router.

Which is a difference between OSPFv2 and OSPFv3?

OSPFv2 stands for Open Shortest Path First version 2 and OSPFv3 stands for Open Shortest Path First version 3. OSPFv2 is the IPv4’s OSPF version, whereas OSPFv3 is the IPv6’s OSPF version. In OSPFv2, many OSPF instances per interface are not supported, whereas in OSPFv3, many OSPF instances per interface are supported.

What does OSPF area contain?

An OSPF area contains one set of link-state information, although each router within the area will process that information individually to form its own SPF tree. OSPF process IDs are locally significant and are created by the administrator.

What is multipoint OSPF point?

The point-to-multipoint mode of operation allows us to then configure selected routers with neighbor / cost commands, identifying a specific cost for the connection to the specified peer.
