In a BIDIR-PIM domain, one DF election per RP is implemented on all PIM-enabled interfaces. As a best practice, do not configure multiple RPs to avoid unnecessary DF elections.

This command sets a limit on the number of BIDIR-PIM RPs. If the number of RPs exceeds the limit, excess RPs do not take effect and can be used only for DF election rather than multicast data forwarding.

Examples

# Set the maximum number of BIDIR-PIM RPs to 3 on the public network.

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 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 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. A larger value represents a lower 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

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.

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

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

Examples

# On the public network, configure the interface with IP address 1.1.1.1 as a C-RP for multicast group s in the ranges of 225.1.0.0/16 and 226.2.0.0/16, and set its priority to 10.

Parameters

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 switch 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 specified in a C-RP advertisement message is 224.1.0.0/16. If the prefix 224.1.0.0 is in the multicast group range specified in the destination field of the ACL, the advertisement message passes the filtering. Otherwise, the advertisement message is discarded.

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

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

Syntax

display interface [ register-tunnel [ interface-number ] ] [ brief [ description | down ] ]

Views

Any view

Predefined user roles

network-admin

network-operator

Parameters

register-tunnel: Displays information about the register-tunnel interface. If you do not specify this keyword, the command displays information about all interfaces on the device.

interface-number: Specifies a register-tunnel interface by its number. The device has only one register-tunnel interface, and the value for this argument is fixed at 0. The command always displays information about Register-Tunnel 0 when you specify the register-tunnel keyword, regardless of whether you specify an interface number.

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.

· You do not specify an ACL.

· The specified ACL does not exist.

· The specified ACL does not have valid rules.

Usage guidelines

CAUTION:

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

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.

You can configure multiple traffic rate thresholds by executing this command multiple times. However, if you specify the same ACL in this command, the most recent configuration takes effect.

Syntax

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

undo static-rp rp-address

Default

No static RPs exist.

Views

PIM view

Predefined user roles

network-admin

Parameters

rp-address: Specifies the IP address of the static RP. This address must be a real and valid unicast IP address, rather than an address on the 127.0.0.0/8 subnet. For a static RP serving BIDIR-PIM, you can specify an unused IP address.

acl-number: Specifies an IPv4 basic ACL number in the range of 2000 to 2999. If you specify an ACL, this command designates the static RP to only 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: Specifies BIDIR-PIM to which the static RP is designated. If you do not specify this keyword, the PIM mode is PIM-SM.

preferred: Gives priority to the static RP if the static RP and the dynamic RP exist at the same time on the network. The dynamic RP takes effect only if no static RP exists on the network. If you do not specify this keyword, the dynamic RP has priority. The static RP takes effect only if no dynamic RP exists on the network or 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 reference the same ACL in this 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

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

<Sysname> system-view
