EIGRP Practice – Basic Session

Protocol Basics
• Proprietary, hybrid routing protocol – DUAL algorithm
• Multicasts hellos to 224.0.0.10
• Rapid convergence
Neighbor Discovery – neighbors must have
• Receives Hellos or ACKs
• Same autonomous system numbers
• Identical metrics (also known as K values)
Metrics – Big Dogs Like Red Meat – Bandwidth and Delay used by default
1. Bandwidth
2. Delay
3. Load
4. Reliability
5. MTU
Topology DB
• Successor
• Feasible successor
Passive interfaces
• Passive-interface command under the routing process – notice no options!
• Will NOT send or receive updates, also means neighbor relationships won’t form
Manually changing bandwidth and delay
1. Go into the interface
2. Bandwidth
3. Delay
Changing Maximum Paths – by default eigrp load balances up to 4 equal cost links
• Router eigrp 10
• Maximum-paths (1-6)
Changing maximum hops – default is 100
• Router eigrp 10
• Metric maximum-hops #
Verification Commands
• Show ip route
• Show ip route eigrp
• Show ip eigrp neighbors
• Show ip eigrp topology
• Debug eigrp packet
• Debug ip eigrp notification
