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.

| RIP v2 |

Hop Count |
Classless |
Bellman-Ford | UDP/520 |
| OSPF |

EGP |
20 (external) 200 (internal) |
Path Attributes (Usually AS-Path) |

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