Types of routing : 
There are three types of routing : 

1) static routing
2) default routing
3) dynamic routing.

1)Static routing :

a)In the static routing ,administrator have to manually provide the destination networks entries in the routing table.
b)It means administrator must know the path of destinations network.
c)It is most reliable type of routing because only administrator knows the route till destination.
d)It is suitable only for small networks.
e)In the large network it is a full time job for a network administrator to update routing table continuously which is a very tough task.
f)The administrator distance or AD value of static routing is 1 .

2) Default routing or default static routing. 
it is another type of static routing. it is used when administrator does not know the information of destination networks and their routes.

Note-
a) Static routing can only perform in the stub router.
b) A router is called stub when it has only one entry and exit path.
Basically uses in DSL or ADSL router.
The AD value of default routing is 1.

3) Dynamic routing: In dynamic routing administrator does not need to manually update the routing table
