1. Add VLANs for routing interfaces.
2. Add IP interfaces with IPv4 addresses to VLANs.

RIPv2 authentication uses plain text 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 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 (interface ip <x>/ ip rip auth type/password); otherwise, the
routing information from authenticated messages is propagated by RIPv1 routers
in an unauthenticated manner.
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.
