How does a router learn about a directly connected network?
Routers add a directly connected route when an interface is configured with an IP address and is activated. Remote routes—These are remote networks connected to other routers. Routes to these networks can be either statically configured or dynamically learned through dynamic routing protocols.
What does the network command do in OSPF?
The network command is used to identify which device interface will be included within the OSPF process and to what area the interface will be assigned to. The correct usage of the network command is vital for the operation of the OSPF network.
What is an ” area ” in OSPF configuration?
An OSPF network can be divided into sub-domains called areas. An area is a logical collection of OSPF networks, routers, and links that have the same area identification.
How are OSPF networks divided into sub-domains?
An OSPF network can be divided into sub-domains called areas. An area is a logical collection of OSPF networks, routers, and links that have the same area identification. A router within an area must maintain a topological database for the area to which it belongs. The router does not have detailed information about network topology outside
What are OSPF areas and virtual links in Cisco?
Stub areas are shielded from external routes but receive information about networks that belong to other areas of the same OSPF domain. You can define totally stubby areas. Routers in totally stubby areas keep their LSDB-only information about routing within their area, plus the default route.
Can you configure OSPF as a broadcast network?
OSPF Network Type. You have the choice of configuring your OSPF network type as either broadcast or NBMA, regardless of the default media type. Using this feature, you can configure broadcast networks as NBMA networks when, for example, you have routers in your network that do not support multicast addressing.
