EIGRP Configuration and Troubleshooting commands

EIGRP Configuration

Syntax

Router(config)#router eigrp <Autonomous-system-number>
Router(config-router)#network <network address>[wild card-mask] (wild card mask is optional)
Router(config-router)#no auto-summary
Router(config-router)#variance <multiplier> (Optional)
 

To influence the metric,it is possible to configure bandwidth on the interfaces:

Router(config)#Interface<interface>
Router(config-if)#bandwidth<BW in kbps>

Configure Default paths in EIGRP
Method 1:
Specify a default network:

Router(config)# ip default-network < network_address >

Method 2:
Create a static default route and then include network 0.0.0.0 in
EIGRP:

Router(config)# ip route 0.0.0.0 0.0.0.0 < next_hop_ip >
Router(config)# router eigrp < as_no >
Router(config-router)# network 0.0.0.0

To view exchange process

Router#debug eigrp packets

To view update process

Router#debug ip eigrp

To view the neighbor table:

Router#show ip eigrp neighbors

To view the EIGRP Topology Table, containing all EIGRP route information: 

Router#  show ip eigrp topology

To view information on EIGRP traffic sent and received on a router: 

Router#  show ip eigrp traffic

To view the bandwidth, delay, load, reliability and MTU values of an interface: 

Router#  show interface s0

To view information specific to the EIGRP protocol: 

Router#  show ip protocols

This command provides us with information on EIGRP timers, EIGRP metrics and summarization

To view the IP routing table: 

Router#  show ip route

To view a specific route within the IP routing table: 

Router#  show ip route 10.3.0.0

To debug EIGRP in realtime: 

Router#  debug eigrp neighbors
Router#  debug eigrp packet
Router#  debug eigrp route
Router#  debug eigrp summary
