acl-number: Basic ACL number, in the range of 2000 to 2999. When an ACL is defined, the source keyword in the rule command specifies a legal BSR source address range.

Description

Use the bsr-policy command to configure a legal BSR address range to guard against BSR spoofing.

Use the undo bsr-policy command to remove the restriction of the BSR address range.

By default, there are no restrictions on the BSR address range, namely all the bootstrap messages received from any source are regarded to be valid.

Examples

# Configure a legal BSR address range on the public network so that only routers on the segment 10.1.1.0/24 can become the BSR.

2: System level

Parameters

interval: BS timeout in seconds, with an effective range of 1 to 2,147,483,647.

Description

Use the c-bsr holdtime command to configure the BS timeout, namely the length of time a C-BSR waits before it must receive a bootstrap message from the BSR.

Use the undo c-bsr holdtime command to restore the default.

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

NOTE:

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.

Parameters

interval: BS period in seconds, with an effective range of 10 to 2,147,483,647.

Description

Use the c-bsr interval command to configure the BS period, namely the interval at which the BSR sends bootstrap messages.

Use the undo c-bsr interval command to restore the default.

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

NOTE:

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.

c-rp interface-type interface-number [ group-policy acl-number | priority priority | holdtime hold-interval | advertisement-interval adv-interval ] * [ bidir ]

undo c-rp interface-type interface-number

View

Public network PIM view, VPN instance PIM view

Default level

2: System level

Parameters

interface-type interface-number: Specifies an interface by its type and number.

acl-number: Basic ACL number, in the range of 2000 to 2999. This ACL defines a range of multicast groups the C-RP is going to serve, rather than defining a filtering rule. Any group range matching 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.

priority: Priority of the C-RP, in the range of 0 to 255 and defaulting to 192. A larger value of this argument means a lower priority.

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

bidir: Configures the C-RP to serve multicast groups in bidirectional PIM mode. Without this argument specified, the C-RP serves groups in PIM-SM.

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.

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

If you do not specify a group range for the C-RP, the C-RP serves all multicast groups.

If you wish a router to be a C-RP for multiple group ranges, you need to include these multiple group ranges in multiple rules in the 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

# In the public network, configure GigabitEthernet 3/1/1 to be a C-RP for multicast groups 225.1.0.0/16 and 226.2.0.0/16, with a priority of 10.

c-rp holdtime (PIM view)

Syntax

c-rp holdtime interval

undo c-rp holdtime

View

Public network PIM view, VPN instance 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 the BSR waits before it must receive a C-RP-Adv message.

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 the C-RP information in 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 on the public network.

<Sysname> system-view

[Sysname] pim

crp-policy (PIM view)

Syntax

crp-policy acl-number

undo crp-policy

View

Public network PIM view, VPN instance PIM view

Default level

2: System level

Parameters

acl-number: Advanced ACL number, in the range of 3000 to 3999. When the ACL is defined, the source keyword in the rule command specifies the address of a C-RP and the destination keyword specifies the address range of the 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 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 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 accepted.

The crp-policy command filters the multicast group ranges advertised by C-RPs based on the group prefixes. For example, if the multicast group range advertised by a C-RP is 224.1.0.0/16 while the legal group range defined by the crp-policy command is 224.1.0.0/30, the multicast groups in the range of 224.1.0.0/16 are allowed to pass.

Related commands: c-rp.

jp-queue-size (PIM view)

Syntax

jp-queue-size queue-size

undo jp-queue-size

View

Public network PIM view, VPN instance PIM view

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.

spt-switch-threshold (PIM view)

Syntax

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

undo spt-switch-threshold [ group-policy acl-number ]

View

Public network PIM view, VPN instance PIM view

Default level

2: System level

Parameters

infinity: Disables SPT switchover.

group-policy acl-number: Specifies a basic 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 multicast groups.

order order-value: Specifies the order of the 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 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 you do not specify an order-value, the order value of the 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 multicast packet from the RPT.

To adjust the order of an existing ACL in the group-policy list, you can use the acl-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 acl-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 multicast group, the first traffic rate configuration matched in sequence takes effect.

Once a multicast forwarding entry is created on the source-side DR, it stops forwarding subsequent 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.

static-rp (PIM view)

Syntax

static-rp rp-address [ acl-number ] [ preferred ] [ bidir ]

undo static-rp rp-address

View

Public network PIM view, VPN instance PIM view

Default level

2: System level

Parameters

rp-address: IP address of the static RP to be configured. This address must be a real, legal unicast IP address, rather than an address on the 127.0.0.0/8 segment. For a static RP serving BIDIR-PIM, you can specify a virtual IP address.

acl-number: Basic ACL number, in the range of 2000 to 2999. If you provide this argument, the configured static RP will serve only those groups that pass the ACL filtering; otherwise, the configured static RP will serve the all-system group 224.0.0.0/4.

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.

bidir: Configures the static RP to serve multicast groups in BIDIR-PIM. Without this argument, the static RP serves groups in PIM-SM.

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.

PIM-SM or 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 the multicast groups.

You can configure multiple static RPs by using this command repeatedly. However, if you execute this command multiple times and specify the same static RP address or reference the same ACL rule, the last configuration will override the previous one. If multiple static RPs have been configured for the same multicast group, the one with the highest IP address will be chosen to serve the multicast group.

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

Related commands: auto-rp enable and display pim rp-info.

Examples

# In the public network, configure the interface with the IP address 11.110.0.6 to be a static RP that serves the multicast groups defined in ACL 2001, and give priority to this static RP in the case of static/dynamic RP conflict.

<Sysname> system-view
