I wanted to take the opportunity to post some core basics for those of you just getting started with Cisco and routing protocols. The table below shows the protocol, the type of routing protocal and the default administrative distance of that protocol.
| Protocol | Type | Admin Distance |
| static | static | 1 |
| EIGRP(summary) | Distance Vector | 5 |
| BGP | Path Vector | 20 |
| EIGRP(internal) | Distance Vector | 90 |
| IGRP | Distance Vector | 100 |
| OSPF | Link State | 110 |
| IS-IS | Link State | 115 |
| RIP | Distance Vector | 120 |
| EIGRP(externall) | Distance Vector | 170 |
| BGP (Internal) | Path Vector | 200 |
