In a routing table, a directly connected network is typically indicated by the code "C." This designation signifies that the route is to a network that is directly attached to the router's interfaces. This allows the router to recognize and forward packets to these networks without needing additional routing protocols.
Directly connected routes are those networks that are directly attached to a router's interfaces. These routes are automatically added to the routing table when a network is configured on a router's interface, and they have the highest priority in routing decisions. They typically have a routing metric of 0, indicating they are the most preferred routes. Additionally, directly connected routes do not require any routing protocols to be established for communication within the same network.
Directly connected routes refer to the network routes that are directly attached to a router's interfaces. These routes are automatically added to the routing table and can be used for communication without the need for additional routing protocols. They are identified by their network address and subnet mask, allowing the router to forward packets to devices on the same local network efficiently.
to identify the directly connected networks that will be announced in RIP updates
Network Specific Routing is a technique in which there is only one entry for all the host connected to the network. Instead of having an entry for each and every hosted connected to the same physical network.
Directly connected networks appear in the routing table when a network interface on a router is configured with an IP address and subnet mask, and the interface is in an "up" state. The router automatically adds these networks to its routing table as local routes, allowing it to route traffic directly to those networks without needing additional configuration or protocols. This ensures that the router can efficiently communicate with devices on those directly connected networks.
They send their routing tables to directly connected neighbors.

show ip route B 200.100.50.0 1.1.1.1 First look the 1.1.1.1 next hop which is directly connected B 1.0.0.0 2.1.1.1 next hope is directly connected So 2.1.1.1 is directly connected and router start the uni-cast routing. this is a recursive lookup
The network as an IP address; the corresponding subnet mask (often shown in shortcut notation, e.g., /24), the next-hop address; the interface through which data must be sent to that network; how it was learned (directly connected, static configuration, or some routing protocol); the administrative distance; the cost or metric.
internal Network
When routing tables adapt to network changes the routing system is called adaptive.
Adopt RIPv2 which is not subject to packet flooding. Implement static routing. Implement a mix of routing protocols to contain the instabilities. Change the topology to a heirarchical design which puts each branch network in its own area.
