IP routing
process by which a packet is forwarded from one network to another.
routers maintain tables that are manually entered (static routes) or dynamically created (dynamic routes)
look at the routing process on page 40.
routing statements
when no routing statement exists, the router drops the packet
the routing statement:
command: IP route
destination network ID: 192.168.10.0
network mask of dest. network: 255.255.255.0
next hop IP address: 200.100.50.253
more on routing statements
when interfaces are configured using the ipunnumbered command, the outbound interface is used instead of next hop
ex. S0/1
