The password to be used for authentication is specified in the
◆
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 receiving
interface must be configured with the same password or authentication
key.
◆
MD5 is a one-way hash algorithm is that takes the authentication key
and produces a 128 bit message digest or “fingerprint.” This makes it
computationally infeasible to produce two messages having the same
message digest, or to produce any message having a given pre-
specified target message digest.
