function.

Configuring zero field check on RIPng packets

Some fields in the RIPng packet must be zero, which are called "zero fields." With zero field check on
RIPng packets enabled, if such a field contains a non-zero value, the entire RIPng packet is
discarded. If you are sure that all packets are reliable, disable the zero field check to reduce the CPU
processing time.
To configure RIPng zero field check:
Step
Enter system view.
1.
Enter RIPng view.
2.
Enable the zero field check.

Configuring the maximum number of ECMP routes

Step

Enter RIPng view.
2.
Configure the maximum

number of ECMP RIPng
routes for load balancing.

Applying IPsec policies for RIPng

To protect routing information and defend attacks, RIPng supports using an IPsec policy to
authenticate protocol packets.
Outbound RIPng packets carry the Security Parameter Index (SPI) defined in the relevant IPsec
policy. A device uses the SPI carried in a received packet to match against the configured IPsec
policy. If they match, the device accepts the packet. Otherwise, it discards the packet and does not
establish a neighbor relationship with the sending device.
You can configure an IPsec policy for a RIPng process or interface. The IPsec policy configured for a
process applies to all packets in the process. The IPsec policy configured on an interface applies to
packets on the interface. If an interface and its process each have an IPsec policy configured, the
interface uses its own IPsec policy.
An IPsec policy used for RIPng can only be in manual mode. For more information, see Security
Configuration Guide.
