How can the default route be generated?
Default routes can also be generated by dynamic routing protocols, such as OSPF and IS-IS. Default routes are used only when no matching routing entry is available for packet forwarding in the routing table. A default route in the routing table is the route to the network 0.0.
Is default route the same as default gateway?
In other words, the default route is the destination that a packet is sent to if the router doesn’t have instructions to send it somewhere else. The default-route is used on routers, while the default gateway is used on hosts. As an example, consider a simple home router that connects your home network to the Internet.
Do routers act independently and route packets as they see fit?
Routers act independently and route packets as they see fit. The various protocols in use on the internet are said to operate in layers in which the protocol(s) at each layer solve one problem related to networked communication, and higher layers are built on top of, and rely on, the lower layers to do their jobs.
What is the default route on a router?
When configuring Routers on the network, the default route is usually added to the device that will access the Internet, and IP packets can route in one direction. If no routing network address exists in the routing table on the router, a Static Route is configured to configure where IP packets go.
What do routers need to know to route a packet?
To be able to route a packet, a router must know at least the following: Destination address to where the packet is destined. Layer 3 protocols such an IP take care of this.
Can a packet be sent directly to the default gateway?
A packet addressed outside of this range, for this example, addressed to 192.168.12.3, cannot travel directly to the destination. Instead it must be sent to the default gateway for further routing to their ultimate destination.
How does a router find a route to a network?
Each time a router receives a packet it inspects the destination IP address and tries to find, by looking in its routing table, a possible route to that IP address. Routers do not send broadcasts looking for the remote networks; therefore if a network is not listed in a routers table,…
