Configuring Advanced EIGRP
Shutting Down EIGRP on an Interface
You can gracefully shut down EIGRP on an interface. This action removes all adjacencies and stops
EIGRP traffic on this interface but preserves the EIGRP configuration.
To disable EIGRP on an interface, use the following command in interface configuration mode:
Configuring Advanced EIGRP

Configuring Authentication in EIGRP
You can configure authentication between neighbors for EIGRP. See the “Authentication” section on
page 8-5.
You can configure EIGRP authentication for the EIGRP process or for individual interfaces. Interface
EIGRP authentication configuration overrides the EIGRP process-level authentication configuration.
BEFORE YOU BEGIN
Ensure that you have enabled the EIGRP feature (see the “Enabling the EIGRP Feature” section on
page 8-9).
Ensure that all neighbors for an EIGRP process share the same authentication configuration, including
the shared authentication key.
Create the key-chain for this authentication configuration. See the Cisco NX-OS Security Configuration
Guide.
Command Purpose
switch(config-if)# {ip | ipv6} eigrp
instance-tag shutdown
Example:
switch(config-router)# ip eigrp Test1
shutdown
Disables EIGRP on this interface. The EIGRP
interface configuration remains. The instance tag can
be any case-sensitive alphanumeric string up to 20
characters.
