Configuring zero field check on RIPng packets
Some fields in the RIPng packet must be zero. These fields 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 trusty, disable the zero field check to reduce the CPU processing time.
To configure RIPng zero field check:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RIPng view. ripng [ process-id ] N/A
3. Enable the zero field check. checkzero
Optional.
Enabled by default.
Configuring the maximum number of ECMP routes
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RIPng view. ripng [ process-id ] N/A
3. Configure the maximum
number of ECMP RIPng routes
for load balancing. maximum load-balancing number
Optional.
16 by default.
Applying IPsec policies for RIPng
To protect routing information and defend attacks, RIPng supports using an IPsec policy to authenticate
protocol packets as follows.
Outbound RIPng packets carry the Security Parameter Index (SPI) defined in the corresponding IPsec
policy. A switch uses the SPI carried in a received packet to match against the configured IPsec policy. If
they match, the switch accepts the packet; otherwise, it discards the packet and thus will not establish a
neighbor relationship with the sending switch.
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.
