• IP Routing
to be configured. The system-routes are of type interface-route means, only the outgoing interface is specified
and do not have the gateway parameter. In the output of the show route command they are flagged with
an “S”.
Dynamic Routes
This kind of routes is assigned to the system either by a routing-protocol (RIP, BGP) or through a device con-
figuration protocol (DHCP, PPP). In the output of the show route command they are flagged with a D. A
dynamic-route is active under the same condition as a static-route.
Show Routes
Execution of show running-config command only displays the static-routes which have been added to the sys-
tem. Neither dynamic-routes nor system-routes are shown there. To get an overview of all routes actually
known by the system the show route command has to be executed.

Basic Static Routing Example
The picture below shows an Internetwork consisting of three routers, a CL2300 in the middle, and the four
autonomous networks, with network addresses 10.1.5.0/16, 172.16.40.0/24, 172.17.100.0/24 and 10.2.5.0/
16. The CL2300 shall be configured for the following IP routing scenario:
All packets for the Workstation with IP address 10.1.5.10 shall be forwarded to the next-hop router Calvin. All
packets for network 10.2.5.0/16 shall be forwarded to the next-hop router Hobbes.
