c-rp ipv6-address [ { group-policy acl6-number | scope scope-id } | priority priority | holdtime hold-interval | advertisement-interval adv-interval ] * [ bidir ]

undo c-rp ipv6-address

View

IPv6 PIM view

Default level

2: System level

Parameters

ipv6-address: IPv6 address of the interface that is to act as a C-RP.

acl6-number: Basic IPv6 ACL number, in the range of 2000 to 2999. This IPv6 ACL defines a range of IPv6 multicast groups the C-RP is going to serve, rather than defining a filtering rule. Any IPv6 multicast group range that matches the permit statement in the ACL will be advertised as an RP served group, while configurations 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: Priority of the C-RP, in the range of 0 to 255 and defaulting to 192. A larger value means a lower priority.

hold-interval: C-RP timeout time, in seconds. The value ranges from 1 to 65,535. If you do not include this argument in your command, the corresponding global setting will be used.

adv-interval: C-RP-Adv interval in seconds, with an effective range of 1 to 65,535. If you do not include this argument in your command, the corresponding global setting will be used.

bidir: Configures the C-RP to serve multicast groups in the bidirectional PIM mode. If you do not specify this argument, the C-RP serves multicast groups in the IPv6 PIM-SM mode.

Description

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

Use the undo c-rp command 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 you do not specify an IPv6 multicast group range for the C-RP, the C-RP will serve all IPv6 multicast groups in the IPv6 non-scoped zone, or it will serve IPv6 multicast groups in the IPv6 global admin-scope zone if IPv6 administrative scoping is configured.

If you wish a router to be a C-RP for multiple group ranges, you need to include these group ranges in multiple rules in the IPv6 ACL corresponding to the group-policy keyword.

If you execute this command repeatedly on the same interface, the last 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.

Parameters

interval: C-RP-Adv interval in seconds, with an effective range of 1 to 65,535.

Description

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

Use the undo c-rp advertisement-interval command 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: C-RP timeout in seconds, with an effective range of 1 to 65,535.

Description

Use the c-rp holdtime command to configure the global C-RP timeout time, namely the length of time for which the BSR waits for a C-RP-Adv message from C-RPs.

Use the undo c-rp holdtime command 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 BSR bootstrap messages, to prevent loss of C-RP information in the BSR bootstrap messages, make sure that the C-RP timeout time is not smaller than the interval at which the BSR sends bootstrap messages. The recommended C-RP timeout setting is 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

[Sysname-pim6] c-rp holdtime 200

crp-policy (IPv6 PIM view)

Syntax

crp-policy acl6-number

undo crp-policy

View

IPv6 PIM view

Default level

2: System level

Parameters

acl6-number: Advanced IPv6 ACL number, in the range of 3000 to 3999. When the IPv6 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 that the C-RP will serve.

Description

Use the crp-policy command to configure a legal C-RP address range and the range of served IPv6 multicast groups, so as to guard against C-RP spoofing.

Use the undo crp-policy command to remove the restrictions in C-RP address ranges and the ranges of served IPv6 multicast groups.

By default, there are no restrictions on C-RP address ranges and the address ranges of served groups, namely all received C-RP messages are assumed to be 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 while 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.

Default level

2: System level

Parameters

queue-size: Maximum number of (S, G) entries in a join/prune message, in the range of 1 to 4,096.

Description

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

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

By default, a join/prune messages contains a maximum of 1,020 (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 may 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 may 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 holdtime join-prune.

undo source-policy

View

IPv6 PIM view

Default level

2: System level

Parameters

acl6-number: Basic or advanced IPv6 ACL number, in the range of 2000 to 3999.

Description

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

Use the undo source-policy command 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 this command is executed repeatedly, the last configuration takes effect.

spt-switch-threshold (IPv6 PIM view)

Syntax

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

undo spt-switch-threshold [ 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 you do not include this option in your command, the configuration will apply on all IPv6 multicast groups.

order order-value: Specifies the order of the IPv6 ACL in the group-policy list, where order-value has an effective range of 1 to (the largest order value in the existing group-policy list + 1), but the value range should not include the original order value of the IPv6 ACL in the group-policy list. If you have assigned an order-value to a certain IPv6 ACL, do not specify the same order-value for another IPv6 ACL; otherwise the system will give error information. If you do not specify an order-value, the order value of the IPv6 ACL will remain the same in the group-policy list.

Description

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

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

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

To adjust the order of an IPv6 ACL that already exists in the group-policy list, you can use the acl6-number argument to specify this IPv6 ACL and set its order-value. This will insert the IPv6 ACL to the position of order-value in the group-policy list. The order of the other existing IPv6 ACLs in the group-policy list will remain unchanged.

To use an IPv6 ACL that does not exist in the group-policy list, you can use the acl6-number argument to specify an IPv6 ACL and set its order-value. This will insert the IPv6 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 takes effect.

Once an IPv6 multicast forwarding entry is created on the source-side DR, it stops forwarding subsequent IPv6 multicast packets in register messages even if a register outgoing interface is available. Therefore, to avoid forwarding failure, do not include the infinity keyword in this command on a static RP or a C-RP.

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

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: IPv6 address of the static RP to be configured. This address must be a real, legal, globally scoped IPv6 unicast address. For a static RP serving IPv6 BIDIR-PIM, you can specify a virtual IPv6 address.

acl6-number: Basic IPv6 ACL number, in the range of 2000 to 2999. If you provide this argument, the configured static RP will serve only those IPv6 multicast groups that pass the filtering; otherwise, the configured static RP will serve the all IPv6 multicast groups.

preferred: Specifies to give priority to the static RP if the static RP conflicts with the dynamic RP. If you do not include the preferred keyword in your command, the dynamic RP will be given priority, and the static RP takes effect on if no dynamic RP exists in the network or when the dynamic RP fails.

Description

Use the static-rp command to configure a static RP.

Use the undo static-rp command 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 IPv6 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 repeatedly. However, if you execute this command multiple times and specify the same static RP address or reference the same IPv6 ACL rule, the last configuration will override the previous one. If multiple static RPs have been configured for the same IPv6 multicast group, the one with the highest IPv6 address will be chosen to serve the group.

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