EIGRP NX-OS / IOS CLI

Cisco IOS CLI	Cisco NX-OS CLI
Enabling the EIGRP Feature

Cisco IOS Software does not have the ability to enable or disable EIGRP.	feature eigrp

Configuring an EIGRP Instance and Router ID

router eigrp 10 eigrp router-id 192.168.1.1	router eigrp 10 router-id 192.168.1.1

Associating a Network with an EIGRP Instance

router eigrp 10 network 192.168.10.0	interface Ethernet2/1 ip address 192.168.10.1/24 ip router eigrp 10

Configuring a Passive Interface

router eigrp 10 network 192.168.10.0 passive-interface GigabitEthernet2/1	interface Ethernet2/1 ip address 192.168.10.1/24 ip router eigrp 10 ip passive-interface eigrp 10

Configuring Interface Authentication (MD5)

key chain eigrp-key key 1 key-string cisco123 interface GigabitEthernet2/1 ip address 192.168.10.1 255.255.255.0 ip authentication mode eigrp 10 md5 ip authentication key-chain eigrp 10 eigrp-key	key chain eigrp-key key 1 key-string 7 070c285f4d06485744 interface Ethernet2/1 ip address 192.168.10.1/24 ip router eigrp 10 ip authentication mode eigrp 10 md5 ip authentication key-chain eigrp 10 eigrp-key

Configuring an EIGRP Distribution List to Filter Routes

ip prefix-list eigrp-10-list seq 5 permit 159.142.1.0/24 router eigrp 10 network 192.168.10.0 distribute-list prefix eigrp-10-list out GigabitEthernet2/1	ip prefix-list eigrp-10-list seq 5 permit 159.142.1.0/24 interface Ethernet2/1 ip address 192.168.10.1/24 ip router eigrp 10 ip distribute-list eigrp 10 prefix-list eigrp-10-list out

Configuring Route Summarization

interface GigabitEthernet2/1 ip address 192.168.10.1 255.255.255.0 ip summary-address eigrp 10 159.142.0.0 255.255.0.0 5	interface Ethernet2/1 ip address 192.168.10.1/24 ip router eigrp 10 ip summary-address eigrp 10 159.142.0.0/16

Generating A Default Route (Conditional)

Cisco IOS Software doesn’t have the same CLI to generate a default route, but redistribution or the ip summary address command can be used to achieve similar results.	router eigrp 10 default-information originate

Configuring Route Redistribution (Permit all Static Routes)

router eigrp 10 redistribute static	router eigrp 10 redistribute static route-map static-to-eigrp route-map static-to-eigrp permit 10

Configuring a VRF Instance for EIGRP Routing

router eigrp 10 address-family ipv4 vrf customer-a autonomous-system 20	router eigrp 10 vrf customer-a autonomous-system 20
