EIGRP configuration example on Nexus 7K switches

EIGRP configuration example on  Nexus 7K switches


Below is the EIGRP configuration example on Nexus switches. Here EIGRP is enable on the directly connected interface between 7K switches.



N7K-1:-

Step1 :- Enable EIGRP feature
N7K-1(config)# feature eigrp
Step2:- Enable EIGRP Process
N7K-1(config)# router eigrp 100
N7K-1(config-router)# router-id 10.1.1.1
Step3:-
Enable eigrp on particular
interface
N7K-12-1(config-router)# int Eth1/1
N7K-2(config-if)#ip address 10.1.1.1 255.255.255.252
N7K-12-1(config-if)# ip router eigrp 100
N7K-2:-

Step4 :- Enable EIGRP feature
N7K-2(config)# feature eigrp
Step5:- Enable EIGRP Process
N7K-2(config)# router eigrp 100
N7K-2(config-router)# router-id 10.1.1.2
Step6:-
Enable EIGRP on particular
interface.
N7K-2(config)# int Eth1/1
N7K-2(config-if)#ip address 10.1.1.2 255.255.255.252
N7K-2(config-if)# ip router eigrp 100
Step7 :-  Optional- Below command can be used if we want
to disable the neighborship on particular interface.
N7K-1(config)# int Eth1/1
N7K-1(config-if)# ip passive-interface eigrp 100 —<
To disable neighborship but Still advertise the network

N7K-1(config-if)# ip eigrp 100 shutdown  –-<< To disable EIGRP on
interface. Both hello packet and advertisement will be stopped.
Verification :-

A.Show ip eigrp
