Parameters

ip-address: Specifies the IP address of a C-RP. You must specify the IP address of a local PIM interface.

advertisement-interval adv-interval: Specifies a C-RP advertisement interval in the range of 1 to 65535 seconds. The default value is 60 seconds.

group-policy ipv4-acl-number: Specifies an IPv4 basic ACL by its number in the range of 2000 to 2999. If you specify an ACL, this command designates the C-RP to IPv4 multicast groups in C-RP advertisement messages that the ACL permits. The C-RP is designated to all IPv4 multicast groups when one of the following conditions exists:

·     You do not specify an ACL.

·     The specified ACL does not exist.

·     The specified ACL does not have valid rules.

holdtime hold-time: Specifies a C-RP lifetime in the range of 1 to 65535 seconds. The default value is 150 seconds.

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

bidir: Specifies BIDIR-PIM to which the C-RP is designated. If you do not specify this keyword, the C-RP provides services for PIM-SM.

Usage guidelines

To designate a C-RP to multiple multicast group ranges, create multiple rules that specify different multicast group ranges in the ACL.

When you configure a rule in the IPv4 basic ACL, follow these restrictions and guidelines:

·     For the rule to take effect, do not specify the vpn-instance vpn-instance option.

·     The source source-address source-wildcard option specifies a multicast group range.

·     Among the other optional parameters, only the fragment keyword and the time-range time-range-name option take effect.

If you execute this command by using the same C-RP address multiple times, the most recent configuration takes effect.

Examples

# Configure the interface with IP address 1.1.1.1 as a C-RP for multicast group ranges 225.1.0.0/16 and 226.2.0.0/16 and set its priority to 10 on the public network.

Parameters

ipv4-acl-number: Specifies an IPv4 advanced ACL number in the range of 3000 to 3999.

Usage guidelines

A C-RP policy filters C-RP advertisement messages to guard against C-RP spoofing.

The device uses only the prefixes of the multicast group ranges in advertisement messages to match the destination field in ACL rules. For example, the multicast group range in an advertisement message is 224.1.0.0/16. If the prefix 224.1.0.0 is in the range specified by the destination field of an ACL rule, the specified C-RPs are designated to this multicast group range.

When you configure a rule in the IPv4 advanced ACL, follow these restrictions and guidelines:

·     For the rule to take effect, do not specify the vpn-instance vpn-instance option.

·     The source source-address source-wildcard option specifies an RP address.

·     The destination dest-address dest-wildcard option specifies a multicast group address.

·     Among the other optional parameters, only the fragment keyword and the time-range time-range-name option take effect.

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

Examples

# Configure a C-RP policy on the public network so that only devices in the range of 1.1.1.1/24 can be C-RPs for the groups in the range of 225.1.1.0/24.

<Sysname> system-view

mdc-admin

mdc-operator

Parameters

register-tunnel [ interface-number ]: Specifies a register-tunnel interface by its number. The device has only one register-tunnel interface, Register-Tunnel 0. If you specify the register-tunnel keyword, this command displays information about Register-Tunnel 0 regardless of whether you specify an interface number. If you do not specify the register-tunnel keyword, this command displays information about all interfaces.

brief: Displays brief information. If you do not specify this keyword, the command displays detailed information.

description: Displays the full interface description. If you do not specify this keyword, the command displays only the first 27 characters of the interface description.

down: Displays information about the interfaces in down state and the reasons why the interfaces are down. If you do not specify this keyword, the command displays information about interfaces in all states.

Usage guidelines

The register-tunnel interface is a virtual interface that is automatically created by the system. You cannot configure it or delete it, but you can display the interface information by using this command.

In the initial stage of multicast source registration, the register-tunnel interface is used to establish a channel between the source-side DR and the RP to transmit multicast register messages. The process of initial source registration is as follows:

1.     After receiving the first multicast data from the source, the source-side DR encapsulates the multicast data into a register message. Then, it forwards the message to the RP through the register-tunnel interface.

2.     The register message reaches RP on the register-tunnel interface on the RP. The RP decapsulates the register message and forwards the multicast data to the receiver hosts. At the same time, the RP learns the IP address of the multicast source.

3.     The RP sends a join message toward the multicast source to build an SPT.

4.     After the SPT is built, the multicast data travels to the RP along the SPT rather than through the register-tunnel interface.

source-policy (PIM view)

Use source-policy to configure a multicast source policy.

Use undo source-policy to restore the default.

Syntax

source-policy ipv4-acl-number

undo source-policy

Default

No multicast source policy exists. The device does not filter multicast data packets.

Views

PIM view

Predefined user roles

network-admin

mdc-admin

Parameters

ipv4-acl-number: Specifies an IPv4 basic or advanced ACL number in the range of 2000 to 3999.

Usage guidelines

A multicast source policy filters multicast data packets to control information available to downstream receivers.

When you configure a rule in the IPv4 ACL, follow these restrictions and guidelines:

·     For the rule to take effect, do not specify the vpn-instance vpn-instance option.

·     In a basic ACL, the source source-address source-wildcard option specifies a source IP address.

·     In an advanced ACL, the source source-address source-wildcard option specifies a source IP address. The destination dest-address dest-wildcard option specifies a multicast group address.

·     Among the other optional parameters, only the fragment keyword and the time-range time-range-name option take effect.

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

Examples

# Configure a multicast source policy on the public network to accept multicast data from source 10.10.1.2 and to deny multicast data from source 10.10.1.1.

<Sysname> system-view

[Sysname] acl basic 2000

[Sysname-acl-ipv4-basic-2000] rule permit source 10.10.1.2 0

spt-switch-threshold (PIM view)

Use spt-switch-threshold to configure a criterion for an RPT-to-SPT switchover.

Use undo spt-switch-threshold to remove criteria for RPT-to-SPT switchovers.

Syntax

spt-switch-threshold { immediacy | infinity } [ group-policy ipv4-acl-number ]

undo spt-switch-threshold [ immediacy | infinity ] [ group-policy ipv4-acl-number ]

Default

The first multicast packet triggers an RPT-to-STP switchover.

Parameters

immediacy: Triggers an RPT-to-STP switchover immediately.

infinity: Disables RPT-to-STP switchover.

group-policy ipv4-acl-number: Specifies an IPv4 basic ACL number in the range of 2000 to 2999. If you specify an ACL, the configuration applies to the multicast groups that the ACL permits. The configuration applies to all multicast groups when one of the following conditions exists:

·     You do not specify an ACL.

·     The specified ACL does not exist.

·     The specified ACL does not have valid rules.

Usage guidelines

When you configure a rule in the IPv4 basic ACL, follow these restrictions and guidelines:

·     For the rule to take effect, do not specify the vpn-instance vpn-instance option.

·     The source source-address source-wildcard option specifies a multicast group address.

·     Among the other optional parameters, only the fragment keyword and the time-range time-range-name option take effect.

After creating multicast routing entries, the source-side DR cannot send multicast data to the RP through register messages. To ensure multicast data forwarding, configure the immediacy keyword on the device that might become the RP.

Examples

# Disable RPT-to-STP switchover on a receiver-side DR on the public network.

Default

No static RPs exist.

Views

PIM view

Predefined user roles

network-admin

mdc-admin

Parameters

rp-address: Specifies the IP address of the static RP. The IP address must be valid and cannot be on the subnet 127.0.0.0/8. For a static PIM-SM RP, you must specify a used IP address. For a static BIDIR-PIM RP, you can specify an unused IP address.

ipv4-acl-number: Specifies an IPv4 basic ACL number in the range of 2000 to 2999. If you specify an ACL, the static RP is designated only to multicast groups that the ACL permits. The static RP is designated to all multicast groups when one of the following conditions exists:

·     You do not specify an ACL.

·     The specified ACL does not exist.

·     The specified ACL does not have valid rules.

bidir: Configures the static RP as a BIDIR-PIM RP. If you do not specify this keyword, this command configures the static RP as a PIM-SM RP.

preferred: Gives priority to the static RP if a dynamic RP also exists on the network. The dynamic RP takes effect only when the static RP fails. If you do not specify this keyword, the dynamic RP has priority, and the static RP takes effect only when the dynamic RP fails.

Usage guidelines

You do not need to enable PIM on an interface that acts as a static RP.

When you configure a rule in the IPv4 basic ACL, follow these restrictions and guidelines:

·     For the rule to take effect, do not specify the vpn-instance vpn-instance option.

·     The source source-address source-wildcard option specifies a multicast group address.

·     Among the other optional parameters, only the fragment keyword and the time-range time-range-name option take effect.

When rules in the ACL used by a static RP change, new RPs are dynamically elected for all multicast groups.

You can configure multiple static RPs by using this command multiple times. However, if you specify the same static RP address or use the same ACL in the command, the most recent configuration takes effect. If you configure multiple static RPs for the same multicast group, the static RP with the highest IP address is used.

Examples

# Configure the interface with IP address 11.110.0.6 as a static RP for multicast group range 225.1.1.0/24 and give priority to this static RP on the public network.

<Sysname> system-view

[Sysname] acl basic 2001

[Sysname-acl-ipv4-basic-2001] rule permit source 225.1.1.0 0.0.0.255

[Sysname-acl-ipv4-basic-2001] quit

[Sysname] pim

timer hello (PIM view)

Use timer hello to set the hello interval globally.

Use undo timer hello to restore the default.

Syntax

timer hello interval

undo timer hello

Default

The hello interval is 30 seconds.

Views

PIM view

Predefined user roles

network-admin

mdc-admin

Parameters

interval: Specifies a hello interval in the range of 0 to 18000 seconds. If you set the value to 0 seconds, the device does not send hello messages.

Usage guidelines

You can set the hello interval globally for all interfaces in PIM view or for an interface in interface view. For an interface, the interface-specific configuration takes priority over the global configuration.

Examples

# Set the global hello interval to 40 seconds on the public network.

<Sysname> system-view

[Sysname] pim

[Sysname-pim] timer hello 40

timer join-prune (PIM view)

Use timer join-prune to set the join/prune interval globally.

Use undo timer join-prune to restore the default.

Syntax

timer join-prune interval

undo timer join-prune

Default

The join/prune interval is 60 seconds.

Views

PIM view

Predefined user roles

network-admin

mdc-admin

Parameters

interval: Specifies a join/prune interval in the range of 0 to 18000 seconds. If you set the value to 0 seconds, the device does not send join or prune messages.

Usage guidelines

You can set the join/prune interval globally for all interfaces in PIM view or for an interface in interface view. For an interface, the interface-specific configuration takes priority over the global configuration.

The configuration takes effect after the current interval ends.

To prevent the upstream neighbors from expiring, you must set the join/prune interval to be less than the joined/pruned state holdtime.

Examples

# Set the global join/prune interval to 80 seconds on the public network.

<Sysname> system-view

[Sysname] pim

[Sysname-pim] timer join-prune 80
