Routing Concepts

IP Routing Table
L - Identifies the address assigned to a router interface. This allows the router to efficiently determine when it receives a packet for the interface instead of being forwarded.

-
- This route is a candidate for a default route.
-
Path Determination
The primary functions of a router are to determine the best path to forward packets based on the information in its routing table,
A directly connected network is added to the routing table when an interface is configured with an IP address and subnet mask (prefix length) and is active (up and up).
Packet Forwarding
.
-
The router examines the destination IP address in the packet header and consults its IP routing table.
-
The router encapsulates the packet in a data link frame and forwards it out the egress interface. The destination could be a device connected to the network or a next-hop router.
However, if there is no matching route entry the packet is dropped.
