Enable zero field check of
RIP-1 packets
Note:
Some fields in a RIP-1 packet must be 0, and they are known as zero fields. For RIP-1,
zero field check is performed on incoming packets, those RIP-1 packets with nonzero
value in a zero filed will not be processed further. As a RIP-2 packet has no zero fields,
this configuration is invalid for RIP-2.
IV. Set RIP-2 packet authentication mode
RIP-2 supports two authentication modes, simple authentication and MD5
authentication.
Simple authentication cannot provide complete security, because the authentication
keys sent along with packets are not encrypted. Therefore, simple authentication
cannot meet high security needs.
Follow these steps to set RIP-2 packet authentication mode:
To do...
Enter system view
Enter interface view
Set RIP-2 packet
authentication mode
V. Configure a RIP neighbor
Follow these steps to configure a RIP neighbor:
To do...
checkzero
Use the command...
system-view
interface interface-type
interface-number
rip authentication-mode
{ simple password | md5
{ rfc2453 key-string |
rfc2082 key-string
key-id } }
Use the command...

Remarks
Required
By default, zero field
check is performed on
RIP-1 packets.

Required
If you specify to use MD5
authentication, you must
specify one of the following
MD5 authentication types:
rfc2453 (this type supports the
packet format defined in RFC
2453)
rfc2082 (this type supports the
packet format defined in RFC
2082)
