I have created a quick reference table for the most popular IGP (Interior Gateway) Routing Protocols. This table covers RIP v1, RIP v2, IGRP, EIGRP, OSPF, and IS-IS. I find it much easier to memorize the details when you can see them all in one place. Thanks to Dan Sheehan for contributing some of the content to this chart. Enjoy!
Note that IS-IS is a CCNP level objective and is not a part of the CCNA objectives. | | RIP V1 | RIP V2 | IGRP | EIGRP | OSPF | IS-IS | | Link State/Distance Vector | Distance Vector | Distance Vector | Distance Vector | Hybrid | Link State | Link State | | Classful/Classless | Classful | Classless | Classful | Classless | Classless | Classless | | Discontiguous Problem | Yes | Yes | Yes | | | | | Administrative Distance | 120 | 120 | 100 | 90 | 110 | | | How does it transfer routing updates? | Broadcast 255.255.255.255 | Multicast 224.0.0.9 | Broadcast 255.255.255.255 | Multicast 224.0.0.10 | Multicast 224.0.0.6 - Routers to DR/BDR 224.0.0.5 - DR to all Routers | CLNS | | How often does it send full updates? (Distance Vector) | 30 Seconds (180 Holddown) | 30 Seconds (180 Holddown) | 90 Seconds (270 Holddown) | | | | | How often does it send hello packets? (Link State) | | | | 5 Seconds (LAN) (15 Holddown) 60 Seconds (WAN) (180 Holddown) | 10 Seconds (LAN) (40 Seconds Flush) 30 Seconds (WAN) (40 Seconds Flush?) | 10 Seconds | | | | | | | | | Metric | Hop Count (Max=15) | Hop Count (Max=15) | Composite Metric (Bandwidth + Delay) (Max=255, Default=128)) | Composite Metric (Bandwidth + Delay) (Max=224, Default=128) | Cost 10^8/Bandwidth | Cost | | Authentication | No | Yes | No | Yes | Yes | Yes | | Bandwidth Usage | High | High | High | Low | Low | Log | | CPU Usage | Low | Low | Low | High | High | High | | Speed to Converge | Slow | Slow | Slow | Fast | Fast | Fast | | Prone to Loops | Yes | Yes | Yes | No | No | No |
