The term “router” in this document refers to a router in a generic sense or a Layer 3 switch.

EA boards (such as LSQ1GP12EA and LSQ1TGX1EA) do not support IPv6 features. 

 

Routing in the Internet is achieved through routers. Upon receiving a packet, a router finds an optimal 

route based on the destination address and forwards the packet to the next router in the path until the 

packet reaches the last router, which forwards the packet to the intended destination host. 

Routing tables play a key role in routing. Each router maintains a routing table, and each entry in the 

table specifies which physical interface a packet destined for a certain destination should go out to 

reach the next hop (the next router) or the directly connected destination. 

Routes in a routing table can be divided into three categories by origin: 

z 

Direct routes: Routes discovered by data link protocols, also known as interface routes. 

z 

Static routes: Routes that are manually configured. 

z 

Dynamic routes: Routes that are discovered dynamically by routing protocols. 

A routing table includes the following key items:  

z 

Destination address: Destination IP address or destination network.
