field in RIP-1 packets
checkzero
Required
Enabled by default
Some fields in a RIP-1 packet must be 0, and they are known as must be zero field. For RIP-1, the
must be zero field is checked for incoming packets, and those RIP-1 packets with this field being
nonzero will not be processed.
Setting RIP-2 packet authentication mode
RIP-2 supports two authentication modes: simple authentication and message digest 5 (MD5)
authentication.
Simple authentication cannot provide complete security, because the authentication keys sent along
with packets that are not encrypted. Therefore, simple authentication cannot be applied where high
security is required.

{ simple password | md5
{ rfc2082 key-string key-id |
rfc2453 key-string } }
Required
If you specify to use MD5 authentication, you
must specify one of the following MD5
authentication types:
z rfc2453 (this type supports the packet format
defined in RFC 2453)
z rfc2082 (this type supports the packet format
defined in RFC 2082)
