Configuring Basic EIGRP
Shutting Down an EIGRP Instance
You can gracefully shut down an EIGRP instance. This action emoves 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 interfacee remains in the EIGRP topology table.
To configure a passive interface for EIGRP, use the following command in interface configuration mode:
Command Purpose
flush-routes
Example:
switch(config)# flush-routes
(Optional) Flushes all EIGRP routes in the unicast
RIB when this EIGRP instance restarts.
restart eigrp instance-tag
Example:
switch(config)# restart eigrp Test1
Restarts the EIGRP instance and removes all
neighbors. The instance tag can be any
case-sensitive alphanumeric string up to 20
characters.
Command Purpose
switch(config-router)# shutdown
Example:
switch(config-router)# shutdown
Disables this instance of EIGRP. The EIGRP router
configuration remains.
Command Purpose
{ip | ipv6} 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.
