UDP Buffer Size of RIP
RIP protocol exchanges the routing information between routers using UDP packets. The
V8102 can be configured theses UDP packets buffer size, use the following command.

Router
Sets the UDP Buffer size value for using RIP.
32768-2147483647: UDP buffer size value
no recv-buffer-size
Restore the default value of UDP buffer size.

Metric Calculation Method
RIPng uses hop count as its metric value. Hop count is the number of routers (number of
hops) from the source router through which data must pass to reach the destination net-
work. RIPng selects the best path to a destination network based only on the number of
hops to the destination network. If you have multiple paths with different bandwidth to the
destination network, then RIP’s best path calculation may become wrong.
The hop count (metric value) of zebos method is increased as soon as it receives the
routing updates. However, zebra (cisco) method increases the hop count (metric) after it
sends the routing updates to the destination network.
To apply the sum of metric in the RIB, use the following command.
Command

Description
metric-sum rib apply
Router

no metric-sum rib apply
Selects the metric calculation method of zebra. (de-
