Step 3. Configure RIPng timers. Command Remarks timers { garbage-collect garbage-collect-value | suppress suppress-value | timeout timeout-value | update update-value } * By default: • The update timer is 30 seconds. • The timeout timer is 180 seconds. • The suppress timer is 120 seconds. • The garbage-collect timer is 120 seconds. Configuring split horizon and poison reverse If both split horizon and poison reverse are configured, only the poison reverse function takes effect. Configuring split horizon Split horizon disables RIPng from sending routes through the interface where the routes were learned to prevent routing loops between neighbors. HP recommends enabling split horizon to prevent routing loops in normal cases. To configure split horizon: Step 1. Enter system view. 2. Enter interface view. 3. Enable split horizon. Command system-view interface interface-type interface-number ripng split-horizon Remarks N/A N/A By default, split horizon is enabled. Configuring poison reverse The poison reverse function enables a route learned from an interface to be advertised through the interface. However, the metric of the route is set to 16, which means the route is unreachable. To configure poison reverse: Step 1. Enter system view. 2. Enter interface view. 3. Enable poison reverse. Command system-view interface interface-type interface-number ripng poison-reverse Remarks N/A N/A By default, poison reverse is disabled. Configuring zero field check on RIPng packets Some fields in the RIPng packet header must be zero. These fields are called "zero fields." You can enable zero field check on incoming RIPng packets. If a zero field of a packet contains a non-zero value, RIPng does not process the packets. If you are certain that all packets are trustworthy, disable the zero field check to save CPU resources. To configure RIPng zero field check: 291
