static routing
static route
R1 (config) # ip route network netmask destination next hop
default route
R1 (config) # ip route 0.0.0.0 0.0.0.0 serial0/0/0 (or other interface)
floating route
R1 (config) # ip route network netmask destination next hop and 2
0 administrative distance directly connected
1 routes static and 2 alternate route
