What are two advantages of using loopback interface on a router with oSPF enabled?
loop back never goes down, helps maintaining adjacency of routers if used with routing protocols
What else can I help you with?
How do you delete a loopback interface on a Cisco router?
(config)#no interface loopback x
What is a characteristic of an IPv4 loopback interface on a Cisco IOS router?
The IPv4 loopback interface on a Cisco IOS router is a virtual interface that is always up and operational, regardless of the physical state of the router's interfaces. It is typically assigned the IP address 127.0.0.1, but any valid IP address in the loopback range (usually 127.0.0.0/8) can be used. This interface is commonly utilized for testing and management purposes, as it allows for local communication within the router itself without relying on physical interfaces. Additionally, it is useful for routing protocol configurations and as a stable endpoint for various network services.
What is an advantage of using a loop back interface on a router with OSPF enabled?
The main advantage of running a loop back interface with OSPF enabled on the router is that there is minimal cost. The IP address will also remain stable in this set up.
What are devices connected to host called?
Configure the router ID on both routers. Configure the R2 router interfaces for area 0. Configure a loopback interface on both routers. Configure the proper subnet masks on the router interfaces.
How is the router ID for an OSPFv3 router determined?
In OSPFv3, the router ID is determined by selecting the highest IP address assigned to an active interface on the router. If no interfaces are available, OSPFv3 will use the highest IPv4 address among the router's loopback interfaces, if configured. If no loopback interfaces are present, and no active IP addresses are available, the router ID remains undefined until one is assigned or the router is restarted. The router ID is essential for uniquely identifying the OSPFv3 router within an OSPF network.
Does a Local Area network uses a router?
The highest MAC address among the active interfaces of the network will be used. There will be no router ID until a loopback interface is configured. The highest IP address among the active FastEthernet interfaces that are running OSPF will be used. The highest IP address among the active interfaces will be used.
What is the router interface that connects to a LAN called?
Outbound interface
Router have a mac id on its interface yes or no?
it should be on back of router!
What is true about the router ID in a single area OSPF network?
The router ID is used to uniquely identify each router in the OSPF routing domain.If no loopback interfaces are configured, the router chooses the highest active IP address of any of its physical interfaces.
Which command enables rip on a router?
A(config)# router rip A(config-router)# passive-interface S0/0 B(config)# router rip B(config-router)# network 192.168.25.48 B(config-router)# network 192.168.25.64 A(config)# router rip A(config-router)# no network 192.168.25.32 B(config)# router rip B(config-router)# passive-interface S0/0 A(config)# no router rip
When a router does not have an interface for the destination network it sends the traffic to where?
If a router has a route in its routing table, it will have a next hop IP address and / or outbound interface. If a router does not have a route in its routing table the packet will be dropped.
What kind of physical interface does the router have?
AUI
