Authentication
RIPv2 authentication uses plaintext password for authentication. If configured using Authentication
password, then it is necessary to enter an authentication key value.
The following method is used to authenticate a RIP message:
 If the router is not configured to authenticate RIPv2 messages, then RIPv1 and unauthenticated
RIPv2 messages are accepted; authenticated RIPv2 messages are discarded.
 If the router is configured to authenticate RIPv2 messages, then RIPv1 messages and
RIPv2 messages which pass authentication testing are accepted; unauthenticated and failed
authentication RIPv2 messages are discarded.
For maximum security, RIPv1 messages are ignored when authentication is enabled; otherwise, the
routing information from authenticated messages is propagated by RIPv1 routers in an
unauthenticated manner.
RIP Configuration Example
Note – An interface RIP disabled uses all the default values of the RIP, no matter how the
RIP parameters are configured for that interface. RIP sends out RIP regular updates to include an
UP interface, but not a DOWN interface.
1. Add VLANs for routing interfaces.
>> # vlan 2
>> (config-vlan)# enable
>> (config-vlan)# member 2
Port 2 is an UNTAGGED port and its current PVID is 1.
Confirm changing PVID from 1 to 2 [y/n]: y
>> (config-vlan)# exit
>> # vlan 3
>> (config-vlan)# enable
>> (config-vlan)# member 3
Port 3 is an UNTAGGED port and its current PVID is 1.
Confirm changing PVID from 1 to 3 [y/n]: y
>> (config-vlan)# exit
