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 trustworthy, disable the zero field check to reduce the CPU processing
time.

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 will 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.
