RIPng configuration commands

checkzero

Use checkzero to enable the zero field check on RIPng packets.

Use undo checkzero to disable the zero field check.

Syntax

checkzero

undo checkzero

Default

The zero field check is enabled.

Views

RIPng view

Default command level

2: System level

Usage guidelines

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 is discarded.

Examples

# Disable the zero field check on RIPng packet headers of RIPng 100.

<Sysname> system-view

[Sysname] ripng 100

[Sysname-ripng-100] undo checkzero

default cost (RIPng view)

Use default cost to specify the default metric of redistributed routes.

Use undo default cost to restore the default.

Syntax

default cost cost

undo default cost

Default

The default metric of redistributed routes is 0.

Views

enable ipsec-policy (RIPng view)

Use enable ipsec-policy to apply an IPsec policy in a RIPng process.

Use undo enable ipsec-policy to remove the IPsec policy from the RIPng process.

Syntax

enable ipsec-policy policy-name

undo enable ipsec-policy

Default

No IPsec policy is configured for the RIPng process.

Views

RIPng view

Default command level

2: System level

Parameters

policy-name: IPsec policy name, a string of 1 to 15 characters.

Usage guidelines

The IPsec policy to be applied must have been configured.

Examples

# Apply IPsec policy policy001 to RIPng process 1.

<Sysname> system-view

[Sysname] ripng 1

[Sysname-ripng-1] enable ipsec-policy policy001

filter-policy export (RIPng view)

Use filter-policy export to define an outbound route filtering policy. Only routes passing the filter can be advertised in the update messages.

Use undo filter-policy export to disable the outbound route filtering.

Syntax

filter-policy { acl6-number | ipv6-prefix ipv6-prefix-name } export [ protocol [ process-id ] ]

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

Default

RIPng does not filter any outbound routing information.

Views

RIPng view

Default command level

2: System level

Parameters

acl6-number: Specifies the number of an ACL to filter advertised routing information, in the range of 2000 to 3999.

ipv6-prefix ipv6-prefix-name: Specifies the name of an IPv6 prefix list used to filter routing information, a string of 1 to 19 characters.

protocol: Filters routes redistributed from a routing protocol, including direct, ripng, and static.

process-id: Process number of the specified routing protocol, in the range of 1 to 65535. This argument is available only when the routing protocol is ripng.

Usage guidelines

With the protocol argument specified, only routing information redistributed from the specified routing protocol will be filtered. Otherwise, all outgoing routing information will be filtered.

To reference 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 rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix.

·     To deny/permit a route with the specified destination and prefix, use rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix destination dest dest-prefix.

The source keyword specifies the destination address of a route, and the destination keyword specifies the prefix of the route. (The prefix must be valid; otherwise, the configuration is ineffective.)

Examples

# Use IPv6 prefix list Filter 2 to filter advertised RIPng updates.

<Sysname> system-view

[Sysname] ripng 100

[Sysname-ripng-100] filter-policy ipv6-prefix Filter2 export

# Configure ACL6 3000 to permit only route 2001::1/128 to pass, and reference ACL6 3000 to filter advertised RIPng updates.

<Sysname> system-view

[Sysname] acl ipv6 number 3000

Use undo filter-policy import to disable inbound route filtering.

Syntax

filter-policy { acl6-number | ipv6-prefix ipv6-prefix-name } import

undo filter-policy import

Default

RIPng does not filter incoming routing information.

Views

RIPng view

Default command level

2: System level

Parameters

acl6-number: Specifies the number of an ACL to filter incoming routing information, in the range of 2000 to 3999.

ipv6-prefix ipv6-prefix-name: Specifies the name of an IPv6 prefix list to filter incoming routes, in the range of 1 to 19 characters.

Usage guidelines

To reference 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 rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix.

·     To deny/permit a route with the specified destination and prefix, use rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix destination dest dest-prefix.

The source keyword specifies the destination address of a route, and the destination keyword specifies the prefix of the route. (The prefix must be valid; otherwise, the configuration is ineffective.)

Examples

# Reference IPv6 prefix list Filter1 to filter incoming RIPng updates.

<Sysname> system-view

[Sysname] ripng 100

[Sysname-ripng-100] filter-policy ipv6-prefix Filter1 import

Parameters

ipv6-address: Destination IPv6 address of the summary route.

prefix-length: 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 falling into 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 GigabitEthernet 1/0/5 and configure a summary with the 35-bit prefix.

<Sysname> system-view

[Sysname] interface gigabitethernet1/0/5

[Sysname-GigabitEthernet1/0/5] ipv6 address 2001:200::3EFF:FE11:6770/64

[Sysname-GigabitEthernet1/0/5] ripng summary-address 2001:200:: 35

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 120 seconds, the timeout timer 180 seconds, and the update timer 30 seconds.

2: System level

Parameters

garbage-collect-value: Interval of the garbage-collect timer in seconds, in the range of 1 to 86400.

suppress-value: Interval of the suppress timer in seconds, in the range of 0 to 86400.

timeout-value: Interval  of the timeout timer in seconds, in the range of 1 to 86400.

update-value: Interval of the update timer in seconds, in the range of 1 to 86400.

Usage guidelines

RIPng is controlled by the following timers:

·     Update timer—Defines the interval between update messages.

·     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.

·     Suppress timer—Defines for how long a RIPng 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 will be 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, 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 be completely deleted from the routing table.

H3C does not recommend changing the default values of these timers under normal circumstances.

The lengths of these timers must be kept consistent on all routers in the network.

Examples

# Configure the update, timeout, suppress, and garbage-collect timers as 5s, 15s, 15s and 30s.
