Enable the check of the must be zero 
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. 

 

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. 

Follow these steps to set RIP-2 packet authentication mode: 

Enter system view  system-view

Enter interface

authentication 
mode 

rip authentication-mode 
{ 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) 

 

Follow these steps to configure RIP to unicast RIP packets:
