Sources of Routing Information
Directly Connected Routes
The entries currently shown to be in the routing tables of routers R1 and R2 are called directly
connected routes.
Static Routes
Dynamic Routing Protocols
Routing Protocol Characteristics
Route Advertisement Method
Distance Vector
Link State
Believability of a Route
The index of believability is called
administrative distance (AD).
Note that lower AD values are more believable than higher AD values.

Interior Versus Exterior Gateway Protocols
Routing Protocol Examples
Routing Information Protocol (RIP)
:
A distance-vector routing protocol that
uses a metric of hop count.
RIP is an IGP.
Open Shortest Path First (OSPF):
A link-state routing protocol that uses a
metric of cost,
which is based on the link speed between two routers.
popular IGP
Intermediate System-to-Intermediate System (IS-IS)
:
This link-state routing
protocol is similar in its operation to OSPF.
IGP
Enhanced Interior Gateway Routing Protocol (EIGRP):
EIGRP is a Cisco
proprietary protoco
l.
Border Gateway Protocol (BGP):
classifies BGP as a distance-vector routing protocol
