Chapter 4 Configuring EIGRP
Configuring Advanced EIGRP
Shutting Down an EIGRP Instance
You can gracefully shut down an EIGRP instance. This action moves all routes and adjacencies but
preserves the EIGRP configuration.
To disable an EIGRP instance, use the following command in router configuration mode:
Configuring a Passive Interface for EIGRP
You can configure a passive interface for EIGRP. A passive interface does not participate in EIGRP
adjacency but the network address for the interface remains in the EIGRP topology table.
To configure a passive interface for EIGRP, use the following command in interface configuration mode:
Shutting Down EIGRP on an Interface

• Configuring EIGRP Stub Routing, page 4-16
Command Purpose
switch(config-router)# shutdown
Example:
switch(config-router)# shutdown
Disables this instance of EIGRP. The EIGRP router
configuration remains.
Command Purpose
ip passive-interface eigrp instance-tag
Suppresses EIGRP hellos, which prevents neighbors
from forming and sending routing updates on an
EIGRP interface. The instance tag can be any
case-sensitive, alphanumeric string up to 20
characters.
Command Purpose
switch(config-if)# ip 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.
