RIP Network Adjustment and Optimization 297
Configuration Tasks Configuring RIP timers
n
When configuring the values of RIP timers, you should take network performance
into consideration and perform consistent configuration on all routers running RIP
to avoid unnecessary network traffic and network route oscillation.
Configuring split horizon
n
Split horizon cannot be disabled on a point-to-point link.
Configuring RIP-1 packet zero field check
n
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.
Setting RIP-2 packet authentication mode
RIP-2 supports two authentication modes, simple authentication and MD5
authentication.
