Understanding routing protocols
Routers can populate their routing tables with directly connected routes or networks that are attached to the local interfaces of a router. However, a router is unable to determine the path/route to a destination network that is not directly connected, such as a remote network on the internet or a network that is attached to another router within an organization.
For instance, the following screenshot shows the routing table of Router-A, which has two directly connected routes/networks on the local router:
Figure 9.4 – Routing table
As shown in the preceding diagram, Router-A contains the 10.10.10.0/30 network, which is directly connected to its GigabitEthernet 0/0 interface, and the 192.168.1.0/24 network, which is directly connected to the GigabitEthernet 0/1 interface.
The following diagram provides a visual representation of the routing table within Router-A:
