A another a very important concept to understand is administrative distance which is essentially the
believability factor of a rocket when multiple routing protocols are configured on a rota and are trying
to put routes into what's called the routing information base or rub also called the writing table.
A router will need to decide who to believe.
If OSPF says go left and Elijah up he says go right to get to a network which is writing protocol does
the route of belief and which route does it insert into the writing table.
In other words what is the trustworthiness or believability of the routing information back to the rotis
receiving.
