Command Usage
• The password to be used for authentication is specified in the ip rip
authentication key command (page 3-140).
• This command requires the interface to exchange routing information
with other routers based on an authorized password. (Note that this
command only applies to RIPv2.)
For authentication to function properly, both the sending and receivin g
interface must be configured with the same password or authentication
key.
