What is Static Default Route :- Static default Route use to advertise  multiple  network in single line
for example we have 4 network to advertise in Router 10.1.1.0/24 , 20.1.1.0./25 , 30.1.1.0/25 , 40.0.0.1/24 so we have to use static route command

ip route 10.1.1.0 255.255.255.0 next hope self

ip route 20.1.1.0 255.255.255.0 next hope self

ip route 30.1.1.0 255.255.255.0 next hope self

ip route 40.1.1.0 255.255.255.0 next hope self

but in default Route use command

ip route 0.0.0.0 0.0.0.0 next hope self

with the help of this command we can advertise complete network


Difference between Static Route to default Static Route

1 :-  Static  route specify destination Network

1 :-  Default static route no specify any destination Network

2 :- Static Route use multiple advertising command

2:-  Default Route use only single advertising command

3:-  Static Route can give any Router on network

3 :- Default Route can give only edge Router ( last router of network they should be only exit link )
