Study Notes

Dynamic Routing Protocols

Routing table updates automatically from connected routers
Send out topology updates when network changes
Requires resources like CPU and bandwidth
OSPF, EIGRP, and RIP are examples of common dynamic routing protocols
Easier network configuration, especially for larger networks
Dynamically chooses alternate routes if a link goes down
Can be used for load balancing across multiple links
Consumes bandwidth because of updates shared between routers
Adds load to router CPU or RAM

Distance Vector Routing Protocols

Calculate best routes using distance, often measured in hops
Advertise routing table to each directly connected neighbor at a set interval
Uses a large amount of bandwidth and slow convergence
When a route becomes unavailable, all routing tables must be updated
Simple setup and administration, ideal for smaller networks
Can be deployed with little management
High bandwidth usage because of full table exchange
Susceptible to routing loops due to outdated information

Link State Routing Protocols

Calculate the best routes using path speed and resource cost of the route
Don't send out entire routing tables; routers notify each other about changes
Uses a three-table system:
Neighbor Table
- Stores information on direct neighbors
Topology Table
- Stores information about the entire network topology, including best and backup routes
Routing Table
- Stores the most efficient routes for each network.
More bandwidth efficient than distance vector protocols
Better understanding of network topology than distance vector protocols
Doesn't send unnecessary information
Provides partial updates when topology changes, reducing bandwidth usage

Routing Information Protocol (RIP)

Used for dynamic routing information exchange
Uses the hop count as its metric
Max hop count is 15 hops
Sends routing updates every 30 seconds
Uses a broadcast method for information transfer
Simple to configure and use
Not suitable for large networks

Enhanced Interior Gateway Routing Protocol (EIGRP)

Cisco proprietary hybrid routing protocol
Combines advantages of both distance-vector and link-state protocols
Uses a metric called "feasible distance"
Calculates routes using both hop count and bandwidth
Uses a multicast method for information transfer
More efficient than RIP for large networks
Provides faster convergence than traditional distance-vector protocols
