CCNA Routing Protocol Comparison Chart Revised

Routing Protocols Comparison for CCNA 

I have always said I was going to make this chart since I draw it on the board for nearly every CCNA class I teach.  Well, here it is.  I may add to it later.

Name

Class
Type
Administrative Distance
Metric
Classful/less
Algorithm
Transport Type
RIP v1
Distance Vector
IGP
120
Hop Count
Classful
Bellman-Ford
UDP/520
RIP v2
Distance Vector
IGP
120
Hop Count
Classless
Bellman-Ford UDP/520
OSPF
Link State
IGP
110
Cost
Classless Dikstra (SPF)
OSPF protocol 89
Integrated IS-IS
Link State
IGP
115
Cost
Classless Dikstra (SPF)
EIGRP
Hybrid (Advanced Distance Vector)
IGP
90 (internal)
170 (external)
Composite (BW + DLY)
Classless DUAL
EIGRP Protocol 88
BGP
Path Vector
EGP
20 (external)
200 (internal)
Path Attributes (Usually AS-Path)
Classless
TCP/179

There is obviously more to it than what you see here but for the CCNA this should be pretty good.
