RIPng commands
checkzero
Use checkzero to enable zero field check on RIPng packets.
Use undo checkzero to disable zero field check.
Syntax
checkzero
undo checkzero
Default
Zero field check is enabled.
Views
RIPng view
Predefined user roles
network-admin
Usage guidelines
Some fields in RIPng packet headers 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 packet.
Examples
# Disable zero field check on RIPng packets for RIPng 100.
<Sysname> system-view
[Sysname] ripng 100
[Sysname-ripng-100] undo checkzero
default cost
Use default cost to configure a default metric for redistributed routes.
Use undo default cost to restore the default.
Syntax
default cost value
undo default cost
Default
The default metric of redistributed routes is 0.
Views
RIPng view
Predefined user roles
network-admin
Parameters
value: Specifies a default metric for redistributed routes, in the range of 0 to 16.
Usage guidelines
When you use the import-route command to redistribute routes from another routing protocol without specifying a metric, the metric specified by the default cost command applies.
Examples
# Configure a default metric of 2 for redistributed routes.
<Sysname> system-view
[Sysname] ripng 100
[Sysname-ripng-100] default cost 2

Parameters
profile-name: Specifies an IPsec profile by its name, a case-sensitive string of 1 to 63 characters.

undo filter-policy export [ protocol [ process-id ] ]
Default

Views
RIPng view
Predefined user roles
network-admin
Parameters
acl6-number: Specifies an ACL by its number in the range of 2000 to 3999 to filter redistributed routes.
protocol: Filters routes redistributed from a routing protocol, including bgp4+, direct, isisv6, ospfv3, ripng, and static.
process-id: Specifies the process ID of the specified routing protocol, in the range of 1 to 65535. This argument is available only when the routing protocol is ripng, ospfv3, or isisv6. The default is 1.
Usage guidelines
If the protocol argument is specified, RIPng filters only routes redistributed from the specified routing protocol. Otherwise, RIPng filters all redistributed routes.
To use an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL in one of the following ways:
· To deny/permit a route with the specified destination, use the rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix command.
· To deny/permit a route with the specified destination and prefix, use the rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix destination dest dest-prefix command.
The source keyword specifies the destination address of a route and the destination keyword specifies the prefix of the route. The specified prefix must be contiguous. Otherwise, the prefix configuration does not take effect.
Examples
# Configure IPv6 ACL 3000 to permit only route 2001::1/128 to pass. Use IPv6 ACL 3000 to filter redistributed routes.
<Sysname> system-view
[Sysname] acl ipv6 number 3000
[Sysname-acl6-adv-3000] rule 10 permit ipv6 source 2001::1 128 destination ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff 128

[Sysname-acl6-adv-3000] quit
[Sysname] ripng 100
[Sysname-ripng-100] filter-policy 3000 export
filter-policy import
Use filter-policy import to configure RIPng to filter received routes. Only routes not filtered can be received.
Use undo filter-policy import to remove the configuration.
Syntax
filter-policy acl6-number import
undo filter-policy import
Default
RIPng does not filter received routes.
Views

Parameters
acl6-number: Specifies an ACL by its number in the range of 2000 to 3999 to filter received routes.
Usage guidelines
To use an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL in one of the following ways:
· To deny/permit a route with the specified destination, use the rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix command.
· To deny/permit a route with the specified destination and prefix, use the rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix destination dest dest-prefix command.
The source keyword specifies the destination address of a route and the destination keyword specifies the prefix of the route. The prefix must be contiguous. Otherwise, the configuration does not take effect.
Examples
# Configure IPv6 ACL 3000 to permit only route 2001::1/128 to pass. Use IPv6 ACL 3000 to filter received routes.

Parameters
protocol: Specifies a routing protocol from which RIPng redistributes routes. It can be bgp4+, direct, isisv6, ospfv3, ripng, or static.
process-id: Specifies a process by its ID in the range of 1 to 65535. The default is 1. This argument is available only when the protocol is isisv6, ospfv3, or ripng.

Parameters
process-id: Specifies a RIPng process by its ID in the range of 1 to 65535. The default value is 1.
Usage guidelines
Before you configure global RIPng parameters, you must create a RIPng process. This restriction does not apply to configuring interface RIPng parameters.

Parameters
only: Advertises only an IPv6 default route (::/0).
originate: Advertises an IPv6 default route (::/0) and other routes.
cost: Specifies a cost for the default route, in the range of 1 to 15. The default is 1.
Usage guidelines
This command enables the interface to advertise a RIPng default route in a route update regardless of whether the default route exists in the local IPv6 routing table.
A RIPng interface configured to advertise a default route does not receive any default routes from its neighbors.
Examples

Predefined user roles
network-admin
Parameters
ipv6-address: Specifies the destination IPv6 address of the summary route.
prefix-length: Specifies the prefix length of the destination IPv6 address of the summary route, in the range of 0 to 128. It indicates the number of consecutive 1s of the prefix, which defines the network ID.
Usage guidelines
Networks on the summary network will not be advertised. The cost of the summary route is the lowest cost among summarized routes.
Examples
# Assign an IPv6 address with the 64-bit prefix to VLAN-interface 100 and configure a summary with the 35-bit prefix.
<Sysname> system-view

timers
Use timers to configure RIPng timers.
Use undo timers to restore the default.
Syntax
timers { garbage-collect garbage-collect-value | suppress suppress-value | timeout timeout-value | update update-value } *
undo timers { garbage-collect | suppress | timeout | update } *
Default
The garbage-collect timer is 120 seconds, the suppress timer is 120 seconds, the timeout timer is 180 seconds, and the update timer is 30 seconds.
Views
RIPng view
Predefines user roles
network-admin
Parameters
garbage-collect-value: Sets the garbage-collect timer in the range of 1 to 86400 seconds.
suppress-value: Sets the suppress timer in the range of 0 to 86400 seconds.
timeout-value: Sets the timeout timer in the range of 1 to 86400 seconds.
update-value: Sets the update timer in the range of 1 to 86400 seconds.
Usage guidelines
RIPng has the following timers:
· Update timer—Interval between update messages.
· Timeout timer—Route aging time. If no update for a route is received before the timer expires, RIPng sets the metric of the route to 16.
· Suppress timer—How long a RIPng route stays in suppressed state. When the metric of a route becomes 16, the route enters the suppressed state. If RIPng receives an update for the route from the same neighbor and the route in the update has a metric less than 16, RIPng uses the route to replace the suppressed route.
· Garbage-collect timer—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 a metric of 16. If no update is announced for that route before the garbage-collect timer expires, RIPng deletes the route from the routing table.
As a best practice, do not change the default values of these timers.
The timer lengths must be kept consistent on all routers in the network.
Examples
# Configure the update, timeout, suppress, and garbage-collect timers as 5 seconds, 15 seconds, 15 seconds, and 30 seconds.
<Sysname> system-view
[Sysname] ripng 1
[Sysname-ripng-1] timers update 5 timeout 15 suppress 15 garbage-collect 30
