R3303-HP HSR6800 Routers Layer 3 - IP Routing Command Reference

62
Usage guidelines
RIP is controlled by the following timers:
• Update timer—Defines the interval between routing updates.
• Timeout timer—Defines the route aging time. If no routing update related to a route is received after
the aging time, the metric of the route is set to 16 in the routing table.
• Suppress timer—Defines how long a RIP route stays in suppressed state. When the metric of a route
is 16, the route enters the suppressed state. In suppressed state, only routes which come from the
same neighbor and whose metric is less than 16 are received by the router to replace unreachable
routes.
• 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, RIP advertises the route
with the routing metric set to 16. If no routing update is announced for that route after the
Garbage-Collect timer expires, the route is deleted from the routing table.
HP recommends not changing the default values of these timers.
The time lengths of these timers must be kept consistent on all routers in the network.
Examples
# Specifies the update, timeout, suppress, and garbage-collect timers as 5, 15, 15 and 30, respectively.
<Sysname> system-view
[Sysname] rip 100
[Sysname-rip-100] timers update 5 timeout 15 suppress 15 garbage-collect 30
