Creating Plain Text Key
Enter the following command to set authentication:
configure interface {cable-mac <mac> | gigabitethernet <slot>/<port> | tengigabitethernet
<slot>/<port>} ip rip authentication key <testkey1>
Where:
testkey1
is a 1–16 character text string used for authentication.
Note: The key can be up to 16 characters long. Every RIP message sent on this interface contains this key and every
incoming message’s validation is dependent on its having this key.
Confirm that the interface is set up to do plain text authentication:
show ip rip
The output should look similar to the following:
VRF Status
default enabled
RIP Interfaces
Interface VRF Df Met Auth Mode State
10.62.1.2 default 0 text active
RIP Timers
VRF default: Update interval is set to 30 seconds.
VRF default: Route invalidation interval is set to 180 seconds.
VRF default: Route flush interval is set to 120 seconds.
MD5 Digest Authentication
Message Digest 5 (MD5) authentication may be enabled for each active or passive interface running RIP in order to add
security to RIP communication. By default it is disabled on each interface.
