View
RIPng view
Parameter
None
Description
Use the checkzero command to enable
the zero field check on RIPng packets.
Use the undo checkzero command to
disable the zero field check.
The zero field check is enabled by default.
Some fields in RIPng packet headers must be
zero. These fields are called zero fields. You can enable the zero field check
on RIPng packet headers. If any such field contains a non-zero value, the RIPng
packet will be discarded.
Example
# Enable the zero field check on RIPng
packet headers.
<Sysname> system-view
[Sysname] ripng 100
[Sysname-ripng-100] checkzero
# Disable the zero field check on RIPng

only:
Indicates that only the IPv6 default route (::/0) is advertised via the

originate:
Indicates that the IPv6 default route (::/0) is advertised without suppressing
other routes.

Description
Use the ripng default-route command
to advertise a default route with the specified routing metric to a RIPng

Parameter
ipv6-address:
IPv6 network address of the summary route.
prefix-length: IPv6 prefix length, in the range of 0 to 128. It indicates the

Description
Use the ripng summary-address
command to configure a summary route advertised on the interface.
Use the undo ripng summary-address
command to remove the summary route.
If the prefix and the prefix length of a
route match the IPv6 prefix, the IPv6 prefix will be advertised instead. Thus,
one route can be advertised on behalf of many routes. After summarization, the
summary route cost is the lowest cost of those summarized routes.

garbage-collect-value: Interval of the garbage-collect timer in seconds, in the range of

timeout-value: Interval of the timeout timer in seconds, in the range of 1 to

update-value:
Interval of the update timer in seconds, in the range of 1 to 86400.
Description
Use the timers command to configure RIPng
timers.
Use the undo timers command to
restore the default.
By default, the interval of the
garbage-collect timer is 240 seconds, that of the suppress timer 120 seconds,
that of the timeout timer 180 seconds, and that of the update timer 30 seconds.
RIPng is controlled by the above four
timers.
l
The update timer defines the interval between
update messages.
l
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.
l
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.
l
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:
l
You are not recommended to change the default
values of these timers under normal circumstances.
l
The lengths of these timers must be kept
consistent on all routers and access servers in the network
Example
# Configure the update, timeout, suppress,
