Full question is: What describes a route learned dynamically It is A identified by the prefix C in the routing table B automatically updated and maintained by routing protocols C unaffected by changes in the topology of the network D an administrative distance of 1
Answer: It is automatically updated and maintained by routing protocols.
When you have routing enabled then you need default route (also calleddefault network or Gateway of Last Resort). You do not need default routeif you don't use routing. For example if you just have one router in your network there is no need for default route. When you have more than one router in a network you need default route.Note: If you connect to WAN (Internet) you need default route. The default route allows connection with Internet. If you are not using WAN and have one router than there is not need for default route but in these days everyone connects to the Internet so most likely your router has default route. When using router to connect to the Internet using DHCP this happens automatically so there will no need to configure default route manually. If you need to manually set default route then use the commands IP default-network or IP route 0.0.0.0 0.0.0.0 .More info can be found at Cisco's site - see the related link below.
A. To configure a route to the first Layer 3 device on the network ...
To route a packet, usually an IP packet, a router compares the destination address to its (the router's) routing table. The router can get entries (rows) in its routing table in three different ways: (1) directly connected networks; (2) static routes (the route was configured manually by an administrator); (3) dynamic routes (the router learned available routes from a neighboring router, using a routing protocol such as RIP or OSPF).
A+ answer All the answers are correct.
--> If the destination network is directly connected, the router forwards the packet to the destination host. --> If no route exists for the destination network and a default route is present, the packet is forwarded to the next-hop router. --> If the originating host has a default gateway configured, the packet for a remote network can be forwarded using that route.
It is a backup route that is stored in the topology table.
Router B uses a Layer 3 network address to route the packet.
R1 will install an EIGRP route using network B in its routing table because the administrative distance of EIGRP is lower than RIP.
* Manually set up a route in a dormant manner. * Stable. * Has no impact made by traffic and transmission failures. * Creates no traffic derived from routing protocols. = dynamic routing: = * Automatically sets up a route. * Can respond to the changes of the network. * Can automatically select the optimized route. * Can automatically select the backup route.
A host uses a default route to transfer data to a host outside the local network when no other route to the destination exists. You may configure the gateway of last resort to achieve this functionality especially if there is a need to route packets outside the LAN. The way to configure a default route to a Cisco Layer 3 device is as follows: Router(config)# ip route <network-address> <subnet-mask> <next-hop-address> Example: Router(config)# ip route 0.0.0.0 0.0.0.0 172.18.3.1
