What is local route in routing table?
The local routes define a route for the one specific IP address configured on the router interface. Each local route has a /32 prefix length, defining a host route, which defines a route just for that one IP. address. For example, the last local route, for 172.16.5.1/32, defines a route that matches only the IP.
How can you view the local routing table?
To display the local routing table:
- Open a command prompt.
- Type route print.
- Press Enter.
- Observe the active routes by destination, network mask, gateway, interface, and metric.
- Close the command prompt to complete this activity.
Is the routing table really a list of routes?
The routing table is just what the name says: a table. That table, in reality, is a list of routes. Each route indicates a destination subnet, as well as how to reach it. Specifically, there is only two pieces of information that tell the router how to reach a destination.
Which is the field to match in the routing table?
Specifically, the field to match is the destination IP address. For each route in the routing table, the router performs a bitwise-AND between the destination IP address and the subnet mask contained in the route. Not quite sure what does this means?
Who is responsible for maintaining a routing table?
Routing tables can be maintained by individual host computers as well as by routers. Each entry in the routing table defines a route. The routing table will contain at least one entry: the default route. This route typically forwards the datagram to the default gateway for the local subnet.
How are far left bits determined in routing table?
For there to be a match between the destination IPv4 address of a packet and a route in the routing table, a minimum number of far left bits must match between the IPv4 address of the packet and the route in the routing table. The subnet mask of the route in the routing table is used to determine the minimum number of far left bits that must match.
