Command Manual – IPv6 Routing
H3C S7500E Series Ethernet Switches
The update timer defines the interval between update messages.
The timeout timer defines the route aging time. If no update message related to a
route is received within the aging time, the metric of the route is set to 16 in the
routing table.
The suppress timer defines how long a RIPng route stays in the suppressed state.
When the metric of a route is 16, the route enters the suppressed state. In the
suppressed state, only routes which come from the same neighbor and whose
metric is less than 16 will be received by the router to replace unreachable routes.
The garbage-collect timer defines the interval from when the metric of a route
becomes 16 to when it is deleted from the routing table. During the garbage-collect
timer length, RIPng advertises the route with the routing metric set to 16. If no
update message is announced for that route before the garbage-collect timer
expires, the route will completely be deleted from the routing table.
Note that:
You are not recommended to change the default values of these timers under
normal circumstances.
The lengths of these timers must be kept consistent on all routers and access
servers in the network
Examples
# Configure the update, timeout, suppress, and garbage-collect timers as 5s, 15s, 15s
and 30s.
<Sysname> system-view
[Sysname] ripng 100
[Sysname-ripng-100] timers update 5
[Sysname-ripng-100] timers timeout 15
[Sysname-ripng-100] timers suppress 15
[Sysname-ripng-100] timers garbage-collect 30
