RIPng Configuration Commands

RIPng Configuration Commands

NOTE:

CE6810LI does not support the RIPng commands.

checkzero (RIPng)

Function

The checkzero command enables zero field check for RIPng packets.

The undo checkzero command disables zero field check for RIPng packets.

By default, zero field check is enabled for RIPng packets.

Format

checkzero

undo checkzero

Parameters

None

Views

RIPng view

Default Level

2: Configuration level

Usage Guidelines

After zero field check is enabled, the switch refuses to process the RIPng packets in which zero fields are not 0. If all RIPng packets are reliable and no zero field needs to be checked, run the undo checkzero command to reduce CPU usage.

Example

# Disable zero field check for RIPng packets.

<HUAWEI> system-view
[~HUAWEI] ripng 1
[*HUAWEI-ripng-1] undo checkzero
Related Topics

default-cost (RIPng)

Function

The default-cost command sets the default cost for imported routes.

The undo default-cost command restores the default value 0.

By default, the default cost of RIPng routes is 0.

Views

RIPng view

Default Level

2: Configuration level

Usage Guidelines

You can configure a route-policy to allow RIPng to import only the routes that match the rout-policy and set attributes for imported routes.

You can run one of the following commands to set the cost of imported routes. The following commands are listed in descending order of priorities.

  • Run the apply cost command to set the cost of routes.

  • Run the import-route (RIPng view) command to set the cost of imported routes.

  • Run the default-cost (RIPng) command to set the default cost of imported routes.

NOTE:

After the import-route direct command is executed, routes to the network segment where the IPv6 address of the management interface belongs are also imported in the RIPng routing table. Therefore, use this command with caution.

Example

# Import routes from IS-IS process 7 and set the cost of imported routes to 7.

<HUAWEI> system-view
[~HUAWEI] ripng 1
[*HUAWEI-ripng-1] import-route isis 7 cost 7

# Import the IBGP routes matching route-policy abc to RIPng process 1 and set the cost of imported routes to 5.

ipsec sa (RIPng)

Function

The ipsec sa command enables IPsec authentication in a RIPng process.

The undo ipsec sa command disables IPsec authentication in a RIPng process.

By default, IPsec authentication is disabled in a RIPng process.

Format

ipsec sa sa-name

undo ipsec sa

Parameters

Parameter Description Value
sa-name Specifies the name of an SA. The name of an SA must already exist.

Views

RIPng view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

As network services develop, security has become an increasing concern. RIPng IPsec uses defined SAs to authenticate RIPng packets received and to be sent. Those packets that fail to be authenticated are discarded, which prevents RIPng networks from being attacked by forged RIPng packets.

If the ipsec sa command is run for a RIPng process, all packets of the process will be authenticated using the SA specified in the command. This means that the IPsec authentication configuration takes effect on all interfaces in the RIPng process.

Prerequisites

An SA has been created using the ipsec sa command.

Precautions

The ripng ipsec sa command takes precedence over the ipsec sa command. If both commands are run in respective views and different SA names are specified, only the configuration of the ripng ipsec sa command takes effect.

Example

# Enable IPsec in a RIPng process and specify sa1 as the SA name.

<HUAWEI> system-view
[~HUAWEI] ipsec sa sa1
[*HUAWEI-ipsec-sa-sa1] quit
[*HUAWEI] ripng 1

maximum load-balancing (RIPng)

Function

The maximum load-balancing command configures the maximum number of equal-cost routes for load balancing.

The undo maximum load-balancing command restores the default setting.

By default, the maximum number of equal-cost routes is 32(64 on the CE6870EI).

Format

maximum load-balancing number

undo maximum load-balancing

Parameters

Parameter Description Value
number Specifies the maximum number of equal-cost routes for load balancing. The value is an integer that ranges from 1 to 32.
NOTE:
The value range on the CE6870EI is 1~64.

Views

undo preference

Parameters

Parameter Description Value
preference Specifies the preference of RIPng routes. The value is an integer that ranges from 1 to 255.
route-policy route-policy-name Specifies the name of a route-policy. The name is a string of 1 to 200 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.

Views

Usage Scenario

As network services develop, security has become an increasing concern. RIPng IPsec uses defined SAs to authenticate RIPng packets received and to be sent. Those packets that fail to be authenticated are discarded, which prevents RIPng networks from being attacked by forged RIPng packets.

To enable IPsec authentication on a specified RIPng interface so that this interface authenticates received RIPng packets and RIPng packets to be sent, run the ripng ipsec sa command.

Prerequisites

An SA has been created using the ipsec sa command.

IPv6 has been enabled on the interface using the ipv6 enable command.

Precautions

The ripng ipsec sa command takes precedence over the ipsec sa command. If both commands are run in respective views and different SA names are specified, only the configuration of the ripng ipsec sa command takes effect.

2: Configuration level

Usage Guidelines

When an interface receives a valid RIPng route, the interface adds a metric to the route before adding the route to the routing table. The metric of this route is changed in the routing table. That is, increasing the metric of an interface also increases the metric of the RIPng route received by the interface.

Before running the ripng metricin command on an interface, run the ipv6 enable command to enable IPv6 on the interface.

Example

# Set the metric that is added to a received RIPng route to 12.

<HUAWEI> system-view
[~HUAWEI] interface vlanif 100
[*HUAWEI-Vlanif100] ipv6 enable
[*HUAWEI-Vlanif100] ripng metricin 12

ripng output

Function

The ripng output command enables an interface to send RIPng packets.

The undo ripng output command disables an interface from sending RIPng packets.

By default, an interface can send RIPng packets.

Format

ripng output

undo ripng output

Parameters

None

Views

Interface view

Default Level

2: Configuration level

Usage Guidelines

When a device running RIPng is connected to a network running other routing protocols, you can run the undo ripng output command on the interface that connects the device to the network to prevent the interface from sending RIPng packets to the network.

Example

# Disable VLANIF100 interface to send RIPng packets.

<HUAWEI> system-view
[HUAWEI] interface vlanif 100
[HUAWEI-Vlanif100] undo ripng output

ripng pkt-transmit

Function

The ripng pkt-transmit command sets the interval for sending Update packets and the number of packets sent each time on a specified interface.

The undo ripng pkt-transmit command restores the default value.

By default, the interval for sending Update packets is 200 ms and the number of packets sent each time is 30 on the RIPng interface.

Format

ripng pkt-transmit { interval interval | number pkt-count } *

undo ripng pkt-transmit

Parameters

Parameter Description Value
interval interval Specifies the interval for sending Update packets. The value is an integer that ranges from 50 to 500, in milliseconds. The default value is 200.
number pkt-count Specifies the number of packets sent each time. The value is an integer that ranges from 25 to 100. The default value is 30.

Views

Default Level

2: Configuration level

Usage Guidelines

Running the ripng pkt-transmit command in the interface view as required can accurately control the interval for sending packets and the number of sent packets. RIPng performance is then improved.

Before running the ripng pkt-transmit command on an interface, run the ipv6 enable command to enable IPv6 on the interface.

Example

# Set the interval for sending Update packets on VLANIF100 to 100 ms and the number of packets sent each time to 50.

<HUAWEI> system-view
[HUAWEI] interface vlanif 100

ripng poison-reverse

Function

The ripng poison-reverse command enables poison reverse for RIPng.

The undo ripng poison-reverse command disables poison reverse for RIPng.

By default, poison reverse is disabled for RIPng.

Format

ripng poison-reverse

undo ripng poison-reverse

Parameters

None

Views

Interface view

Default Level

2: Configuration level

Usage Guidelines

After poison reverse is configured, the route learned from an interface is also sent to the neighboring device through the same interface. The metric of this route is set to 16, indicating that the route is unreachable.

When split horizon and poison reverse are configured on the same interface, only poison reverse takes effect.

Before running the ripng poison-reverse command on an interface, run the ipv6 enable command to enable IPv6 on the interface.

Example

# Enable poison reverse for RIPng Update packets.

<HUAWEI> system-view
[~HUAWEI] interface vlanif 100
[*HUAWEI-Vlanif100] ipv6 enable
[*HUAWEI-Vlanif100] ripng poison-reverse

ripng split-horizon

Function

The ripng split-horizon command enables split horizon for RIPng.

The undo ripng split-horizon command disables split horizon for RIPng.

y default, split horizon is enabled except on the NBMA network.

Format

ripng split-horizon

undo ripng split-horizon

Parameters

None

Views

Interface view

Default Level

2: Configuration level

Usage Guidelines

After split horizon is enabled, a route is blocked if the route is advertised through the interface that learns the route. The split horizon mechanism avoids routing loops between adjacent neighbors.

When poison reverse and split horizon are configured on the same interface, only poison reverse takes effect.

Before running the ripng split-horizon command on an interface, run the ipv6 enable command to enable IPv6 on the interface.

Example

# Enable split horizon for RIPng Update packets.

<HUAWEI> system-view
[~HUAWEI] interface vlanif 100
[*HUAWEI-Vlanif100] ipv6 enable
[*HUAWEI-Vlanif100] ripng split-horizon

# Enable split horizon for RIPng Update packets.

ripng summary-address

Function

The ripng summary-address command configures a RIPng device to advertise summarized IPv6 addresses on an interface.

The undo ripng summary-address command deletes this configuration.

By default, a RIPng switch does not advertise summarized IPv6 addresses.

Format

ripng summary-address ipv6-address prefix-length [ avoid-feedback ]

undo ripng summary-address ipv6-address prefix-length

Parameters

Parameter Description Value
ipv6-address Specifies a summarized IPv6 address. The value is a 32-digit hexadecimal number, in the X:X:X:X:X:X:X:X format.
prefix-length Specifies the prefix length of an IPv6 address. The value is an integer that ranges from 0 to 128.
avoid-feedback Disables an interface from learning the same summarized route. -

Views

Interface view

Default Level

2: Configuration level

Usage Guidelines

If the prefix and prefix length of a route match the defined IPv6 prefix, the defined IPv6 prefix is advertised instead of the route. As a result, multiple routes are replaced by a single route that has a lower metric.

After the keyword avoid-feedback is specified, an interface no longer learns the summarized route with the same IP address as the advertised summarized IP address. This avoids routing loops.

This command can take effect only after IPv6 is enabled for the RIPng process and interfaces.

Example

# Configure IPv6 address FC00:200::3EFF:FE11:6770 for VLANIF100, set the prefix length to 64 bits, and summarize the configured IPv6 address as an IPv6 address with prefix FC00:200::/35 in RIPng process 100.

timers ripng

Function

The timers ripng command configures RIPng timers.

The undo timers ripng command restores the default values of timers.

By default, the interval for sending RIPng Update packets is 30s, the aging time of routes is 180s, the suppress time is 0s, and the time for deleting routes from an IPv6 routing table is 120s.

Format

timers ripng update age suppress garbage-collect

undo timers ripng

Parameters

Parameter Description Value
update Specifies the interval for sending Update packets. This parameter is the basic timing parameter of routing protocols. The value is an integer that ranges from 1 to 86400, in seconds. The default value is 30 seconds.
age Specifies the aging time of routes. The value of age must be at least three times the value of update. If no Update packet of a route is received within the aging time, the route becomes invalid (unreachable). The value is an integer that ranges from 1 to 86400, in seconds. The default value is 180 seconds.
suppress Specifies the period during which the advertisement of optimal route is suppressed. The value is an integer ranging from 0 to 86400, in seconds. In the current version, the value is fixed to 0 seconds.
garbage-collect Specifies the time from when a route is found invalid until it is deleted from the routing table. The value is an integer that ranges from 1 to 86400, in seconds. The default value is 120 seconds.

Views

RIPng view

Default Level

2: Configuration level

Usage Guidelines

The command can take effect only after global IPv6 is enabled.

If the values of the preceding four timers are set improperly, route flapping occurs. The relationship of the values of the timers is: update < age and < garbage-collect. For example, if the update time is longer than the aging time, switchs cannot inform neighbors on time if RIP routes change during the update time.

Example

# Set values for RIPng timers.

<HUAWEI> system-view
[~HUAWEI] ripng 100
[*HUAWEI-ripng-100] timers ripng 5 15 0 30
