Chapter 8: Routing Pg 259 - End

IS-IS
- Intermediate system to Intermediate System (IS-IS): allows you to use a link state dynamic protocol without using OSPF
- uses the concept of areas and send-only updates to routing tables

EIGRP - The Lone Hybrid 
- Enhanced Interior Gateway Routing Protocol (EIGRP)
- replaced Interior Gateway Routing Protocol (IGRP)

Set Up of the WAN
- need to know the network IDs for each side of the router
- WAN invariably connects to an ISP

Set Up the LAN
- need to choose a netowrk ID
- need to assign the correct IP information to the LAN-side NIC

Configure A Dynamic Protocol
- dynamic protocols are tied to indiviudal NICs
- make sure the two NICs are configured to use the same dynamic routing protocol

Things To Remember:

1. A router is a peice of hardware that forwards packets based on IP address
2. A router can interconnect different layer 2 technologies
3. Port Address Translation enables you to share a single public IP address with many computers
4. distance vector routing protocols use hop count to determine the best route.
5. OSPF bases routes on speed and sends only route changes to minimize traffic.
6. Area 0 is known as the backbone.
7. Yost cable was invented to standardize the serial console interface.
