Configuring RIP
2. interface interface-type slot/port
3. ip rip authentication mode{text | md5}
4. ip rip authentication keychain key
5. copy running-config startup-config
DETAILED STEPS
The following example shows how to create a key chain and configure MD5 authentication on a RIP
interface:
switch# config t
switch(config)# key chain RIPKey
switch(config)# key-string myrip
switch(config)# accept-lifetime 00:00:00 Jan 01 2000 infinite
switch(config)# send-lifetime 00:00:00 Jan 01 2000 infinite
switch(config)# interface ethernet 1/2
switch(config-if)# ip rip authentication mode md5
switch(config-if)# ip rip authentication keychain RIPKey
switch(config-if)# copy running-config startup-config
Configuring a Passive Interface
You can configure a RIP interface to receive routes but not send route updates by setting the interface to
passive mode.
Command Purpose
Step 1
config t
Example:
switch# config t
switch(config)#
Enters configuration mode.
Step 2
interface interface-type slot/port
Example:
switch(config)# interface ethernet 1/2
switch(config-if)#
Enters interface configuration mode.
Step 3
ip rip authentication mode {text | md5}
Example:
switch(config-if)# ip rip authentication
mode md5
Sets the authentication type for RIP on this interface as
cleartext or MD5 authentication digest.
Step 4
ip rip authentication keychain key
Example:
switch(config-if)# ip rip authentication
keychain RIPKey
Configures the authentication key used for RIP on this
interface.
Step 5
copy running-config startup-config
Example:
switch(config-if)# copy running-config
startup-config
(Optional) Saves this configuration change.
