Cisco ICND2 - Configure, verify and troubleshoot EIGRP

Next routing protocol up is configure, verify and troubleshoot EIGRP.

Using the same layout from OSPF, we will re-configure for EIGRP.

First turn off ospf on the routers

configure terminal
no router ospf 1

Configuring EIGRP is similar to that of OSPF.

RouterA

configure terminal
router eigrp 1
network 10.0.3.68 0.0.0.3
network 10.0.3.72 0.0.0.3
network 10.0.3.32 0.0.0.31
network 10.0.0.0 0.0.0.255
no auto-summary

RouterB

configure terminal
router eigrp 1
network 10.0.1.0 0.0.0.255
network 10.0.3.64 0.0.0.3
network 10.0.3.0 0.0.0.31
network 10.0.3.68 0.0.0.3
no auto-summary

RouterC

configure terminal
router eigrp 1
network 10.0.2.0 0.0.0.255
network 10.0.3.64 0.0.0.3
network 10.0.3.72 0.0.0.3
no auto-summary

Verify EIGRP

Router A routing table:

Router B routing table:

Router C routing table:

show ip route eigrp
show ip eigrp neighbors
show ip eigrp topology
show ip protocols
ping remote computers/WAN links

Troubleshoot EIGRP

Autonomous number must match
Like OSPF, the EIGRP timers must match
If routing tables not advertising correct routes, auto summary may be enabled, I like to turn auto summary off
debug eigrp packet
debug ip eigrp neighbor
