c-bsr holdtime (IPv6 PIM view)

Syntax

c-bsr holdtime interval

undo c-bsr holdtime

View

IPv6 PIM view

Default level

2: System level

Parameters

interval: Specifies a BS timeout value in seconds, in the range of 1 to 2147483647.

Description

Use c-bsr holdtime to configure the BS timeout (length of time that the C-BSRs wait for a bootstrap message from the BSR).

Use undo c-bsr holdtime to restore the default.

By default, the BS timeout value is determined by this formula: BS timeout = BS period × 2 + 10.

The default BS period is 60 seconds, so the default BS timeout = 60 × 2 + 10 = 130 (seconds).

Related commands: c-bsr and c-bsr interval.

Examples

# Set the BS timeout to 150 seconds.

Parameters

interval: Specifies a BS period in seconds, in the range of 10 to 2147483647.

Description

Use c-bsr interval to configure the BS period (interval at which the BSR sends bootstrap messages).

Use undo c-bsr interval to restore the default.

By default, the BS period value is determined by this formula: BS period = (BS timeout – 10) / 2.

The default BS timeout is 130 seconds, so the default BS period = (130 – 10) / 2 = 60 (seconds).

Related commands: c-bsr and c-bsr holdtime.

undo c-rp ipv6-address

View

IPv6 PIM view

Default level

2: System level

Parameters

ipv6-address: Specifies the IPv6 address of the interface that will act as a C-RP.

acl6-number: Specifies a basic IPv6 ACL number in the range of 2000 to 2999. This ACL defines a range of IPv6 multicast groups to which the C-RP is designated, rather than defining a filtering rule. Any IPv6 multicast group range that matches the permit statement in the ACL will be advertised as a group range to which the C-RP is designated, but the configuration matching other statements like deny will not take effect.

scope-id: Specifies the value of the Scope field, in the range of 3 to 15.

priority: Specifies the priority of the C-RP, in the range of 0 to 255. The default is 192. A larger value represents a lower priority.

hold-interval: Specifies a C-RP timeout time in seconds, in the range of 1 to 65535. If this argument is not specified, the corresponding global setting is used.

adv-interval: Specifies a C-RP-Adv interval in seconds, in the range of 1 to 65535. If this argument is not specified, the corresponding global setting is used.

bidir: Specifies the bidirectional PIM mode. If this argument is not specified, the IPv6 PIM mode is IPv6 PIM-SM. This keyword is not supported.

Description

Use c-rp to configure the specified interface as a C-RP.

Use undo c-rp to remove the related C-RP configuration.

No C-RPs are configured by default.

IPv6 PIM-SM must be enabled on the interface to be configured as a C-RP.

If the IPv6 multicast group range for the C-RP is not specified, the C-RP provides services for all IPv6 multicast groups in the IPv6 non-scoped zone, or it provides services for IPv6 multicast groups in the IPv6 global admin-scope zone if IPv6 administrative scoping is configured.

If you want a device to be a C-RP for multiple group ranges, you need to include these group ranges in multiple rules in the ACL corresponding to the group-policy keyword.

If you execute this command multiple times on the same interface, the most recent configuration takes effect.

Related commands: c-bsr.

Examples

# Configure the interface with the IPv6 address of 2001::1 to be a C-RP for IPv6 multicast group FF0E:0:1391::/96, with a priority of 10.

2: System level

Parameters

interval: Specifies a C-RP-Adv interval in seconds, in the range of 1 to 65535.

Description

Use c-rp advertisement-interval to configure the interval at which C-RP-Adv messages are sent.

Use undo c-rp advertisement-interval to restore the default.

By default, the C-RP-Adv interval is 60 seconds.

Related commands: c-rp.

Examples

# Set the global C-RP-Adv interval to 30 seconds.

<Sysname> system-view

c-rp holdtime (IPv6 PIM view)

Syntax

c-rp holdtime interval

undo c-rp holdtime

View

IPv6 PIM view

Default level

2: System level

Parameters

interval: Specifies a C-RP timeout in seconds, in the range of 1 to 65535.

Description

Use c-rp holdtime to configure the global C-RP timeout time (length of time that the BSR waits for a C-RP-Adv message from C-RPs).

Use undo c-rp holdtime to restore the default.

By default, the C-RP timeout time is 150 seconds.

Because a non-BSR router refreshes its C-RP timeout time through bootstrap messages, to prevent loss of C-RP information in bootstrap messages, make sure that the C-RP timeout time is not smaller than the interval at which the BSR sends bootstrap messages. H3C recommends that you set the C-RP timeout to 2.5 times the BS period or longer.

Related commands: c-bsr interval and c-rp.

Examples

# Set the global C-RP timeout time to 200 seconds.

<Sysname> system-view

[Sysname] pim ipv6

crp-policy (IPv6 PIM view)

Syntax

undo crp-policy

View

IPv6 PIM view

Default level

2: System level

Parameters

acl6-number: Specifies an advanced IPv6 ACL number in the range of 3000 to 3999. When the ACL is defined, the source keyword in the rule command specifies the IPv6 address of a C-RP and the destination keyword specifies the IPv6 address range of the IPv6 multicast groups to which the C-RP is designated.

Description

Use crp-policy to configure a legal C-RP address range and the IPv6 multicast group ranges to which the C-RP is designated. This command guards against C-RP spoofing.

Use undo crp-policy to remove the restrictions in C-RP address ranges and the IPv6 multicast group ranges to which the C-RP is designated.

By default, no restrictions are defined for C-RP address ranges and the IPv6 multicast group range to which the C-RP is designated. All received C-RP messages are regarded legal.

The crp-policy command filters the IPv6 multicast group ranges advertised by C-RPs based on the group prefixes. For example, if the IPv6 multicast group range advertised by a C-RP is FF0E:0:1::/96 and the legal IPv6 multicast group range defined by the crp-policy command is FF0E:0:1::/120, the IPv6 multicast groups in the range of FF0E:0:1::/96 are allowed to pass.

Related commands: c-rp.

Examples

# Configure a C-RP policy so that only devices in the IPv6 address range of 2001::2/64 can be C-RPs that provide services for IPv6 multicast groups in the address range of FF03::101/64.

Parameters

acl6-number: Specifies a basic IPv6 ACL number in the range of 2000 to 2999.

Description

Use embedded-rp to enable embedded RP.

Use undo embedded-rp to disable embedded RP or restore the default.

By default, embedded RP is enabled for IPv6 multicast groups in the default embedded RP address scopes.

The default embedded RP address scopes are FF7x::/12 and FFFx::/12. Here "x" refers to any legal address scope. For more information about the scope field, see "Multicast overview."

When you use the embedded-rp command without specifying acl6-number, the embedded RP feature will be enabled for all the IPv6 multicast groups in the default embedded RP address scopes. If the acl6-number argument is specified, the embedded RP feature will be enabled for only those IPv6 multicast groups that are within the default embedded RP address scopes and pass the ACL check.

When you use the undo embedded-rp command without specifying acl6-number, the embedded RP feature will be disabled for all the IPv6 multicast groups. If the acl6-number argument is specified, this command will restore the default.

undo jp-queue-size

View

IPv6 PIM view

Default level

2: System level

Parameters

queue-size: Specifies the maximum number of (S, G) entries in a join/prune message, in the range of 1 to 4096.

Description

Use jp-queue-size to configure the maximum number of (S, G) entries in a join/prune message.

Use undo jp-queue-size to restore the default.

By default, a join/prune messages contains a maximum of 1020 (S, G) entries.

When you use this command, take the following into account:

· The size of the forwarding table. In a network that does not support packet fragmentation, if you configure a large queue-size, a join/prune message might contain a large number of groups, causing the message length to exceed the MTU of the network. As a result, the products that do not support fragmentation will drop the join/prune message.

· The (S, G) join/prune state hold time on the upstream device. If you configure a small queue size, the outgoing interface of the corresponding entry might have been pruned due to timeout before the last join/prune message in a queue reaches the upstream device.

Related commands: holdtime join-prune, jp-pkt-size, and pim ipv6 holdtime join-prune.

Parameters

acl6-number: Specifies a basic or advanced IPv6 ACL number in the range of 2000 to 3999.

Description

Use source-policy to configure an IPv6 multicast data filter.

Use undo source-policy to remove the configured IPv6 multicast data filter.

By default, no IPv6 multicast data filter is configured.

If you specify a basic ACL, the device filters all the received IPv6 multicast packets based on the source address, and discards packets that fail the source address match.

If you specify an advanced ACL, the device filters all the received IPv6 multicast packets based on the source and group addresses, and discards packets that fail the match.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Configure the router to accept IPv6 multicast packets originated from 3121::1 and discard IPv6 multicast packets originated from 3121::2.

spt-switch-threshold (IPv6 PIM view)

Syntax

spt-switch-threshold infinity [ group-policy acl6-number [ order order-value ] ]

undo spt-switch-threshold [ infinity ] [ group-policy acl6-number ]

View

IPv6 PIM view

Default level

2: System level

Parameters

infinity: Disables SPT switchover.

group-policy acl6-number: Specifies a basic IPv6 ACL number in the range of 2000 to 2999. If this option is not specified, the configuration will apply on all IPv6 multicast groups.

order order-value: Specifies the order of the ACL in the group-policy list. The value range for the order-value argument is 1 to the largest order value in the existing group-policy list plus 1, but it should not include the original order value of the ACL in the group-policy list. If you have assigned an order-value to a certain ACL, do not specify the same order-value for another ACL. Otherwise the system will give error information. If the argument is not specified, the order value of the ACL will remain the same in the group-policy list.

Description

Use spt-switch-threshold to configure the SPT switchover parameters.

Use undo spt-switch-threshold to restore the default.

By default, the device switches to the SPT immediately after it receives the first IPv6 multicast packet.

CAUTION:

If the switch is an RP, disabling switchover to SPT might cause multicast traffic forwarding failures on the source-side DR. When disabling switchover to SPT, be sure you fully understand its impact on your network.

To adjust the order of an ACL that already exists in the group-policy list, you can use the acl6-number argument to specify this ACL and set its order-value. This will insert the ACL to the position of order-value in the group-policy list. The order of the other existing ACLs in the group-policy list will remain unchanged.

To use an ACL that does not exist in the group-policy list, you can use the acl6-number argument to specify an ACL and set its order-value. This will insert the ACL to the position of order-value in the group-policy list. If you do not include the order order-value option in your command, the ACL will be appended to the end of the group-policy list.

If you use this command multiple times on the same IPv6 multicast group, the first traffic rate configuration matched in sequence will take effect.

Examples

# Disable SPT switchover on a switch that will never become an RP.

[Sysname] pim ipv6

[Sysname-pim6] spt-switch-threshold infinity

Syntax

static-rp ipv6-rp-address [ acl6-number ] [ preferred ]

undo static-rp ipv6-rp-address

View

IPv6 PIM view

Default level

2: System level

Parameters

ipv6-rp-address: Specifies the IPv6 address of the static RP to be configured. This address must be a real, valid, globally scoped IPv6 unicast address. For a static RP that provides services for IPv6 BIDIR-PIM, you can specify a virtual IPv6 address.

acl6-number: Specifies a basic IPv6 ACL number in the range of 2000 to 2999. If this argument is specified, the configured static RP provides services for only those IPv6 multicast groups that pass the filtering. Otherwise, the configured static RP provides services for the all IPv6 multicast groups.

preferred: Specifies to give priority to the static RP if the static RP conflicts with the dynamic RP. If the preferred keyword is not specified, the dynamic RP will be given priority, and the static RP takes effect only if no dynamic RP exists in the network or when the dynamic RP fails.

Description

Use static-rp to configure a static RP.

Use undo static-rp to configure a static RP.

By default, no static RP is configured.

IPv6 PIM-SM or IPv6 PIM-DM cannot be enabled on an interface that serves as a static RP.

When the ACL rule applied on a static RP changes, a new RP must be elected for all IPv6 multicast groups.

You can configure multiple static RPs by carrying out this command multiple times. However, if you execute this command multiple times and specify the same static RP address or reference the same ACL rule, the most recent configuration takes effect. If multiple static RPs have been configured for the same IPv6 multicast group, the one with the highest IPv6 address will be chosen to provide services for the group.

You can configure up to 50 static RPs on the same device.

Related commands: display pim ipv6 rp-info.

Examples

# Configure the interface with an IPv6 address of 2001::2 as a static RP to provide services for the IPv6 multicast groups in the address range of FF03::101/64 defined in basic IPv6 ACL 2001, and give priority to this static RP in the case of static/dynamic RP conflict.
