View

Public instance PIM view, VPN instance PIM view

Default Level

2: System level

Parameters

interface-type interface-number: Specifies an interface, the IP address of which will be advertised as a C-RP address.

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 0. A larger value of this argument means a lower priority.

hold-interval: C-RP timeout time, in seconds. The effective range is 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.

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.

Note that:

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

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

l 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.

l If you carry out this command repeatedly on the same interface, the last configuration will take effect.

Related commands: c-bsr.

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 system 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 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-rp, c-bsr interval.

View

Public instance 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.

Note that 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.

Default Level

1: Monitor level

Parameters

all-instance: Specifies all instances.

vpn-instance vpn-instance-name: Specifies a VPN instance. A VPN instance name is a case sensitive string of up to 31 characters and must not contain any space.

group-address: Address of the multicast group of which the RP information is to be displayed, in the range of 224.0.1.0 to 239.255.255.255. If you do not provide a group address, this command will display the RP information corresponding to all multicast groups.

Description

Use the display pim rp-info command to view the RP information.

Note that:

l If neither all-instance nor vpn-instance is specified, this command will display the information on the public instance.

l The RP information includes the information of RPs dynamically found by the BSR mechanism and static RPs.

l Because a non-BSR router refreshes its local RP-Set only based on the received BSR bootstrap messages, the system does not delete an RP even if its expiry time is 0. Instead, the system waits for the next bootstrap message from the BSR: if the bootstrap message does not contain information of the RP, the system will delete it.

Examples

# View the RP information corresponding to the multicast group 224.0.1.1 in the public instance.

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

l 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.

l The (S, G) join/prune timeout 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: jp-pkt-size, holdtime join-prune, pim holdtime join-prune.

Description

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

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

By default, no multicast data filter is configured.

Note that:

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

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

l If this command is executed repeatedly, the last configuration will take effect.

spt-switch-threshold infinity (PIM view)

Syntax

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

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

View

Public instance PIM view, VPN instance PIM view

Default Level

2: System level

Parameters

group-policy acl-number: Specifies a basic ACL, 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 infinity command to configure disabling the SPT switchover.

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

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

Note that:

l 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.

l 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.

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

l For an S7500E series Ethernet switch, once a multicast forwarding entry is created, subsequent multicast data will not be encapsulated in register messages before being forwarded even if a register outgoing interface is available. Therefore, to avoid forwarding failure, do not use spt-switch-threshold infinity command on a switch that may become an RP (namely, a static RP or a C-RP).

Examples

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

static-rp (PIM view)

Syntax

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

undo static-rp rp-address

View

Public instance 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 legal unicast IP address, rather than an address on the 127.0.0.0/8 segment.

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 only 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.

Note that:

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

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

l You can configure multiple static RPs by using this command repeatedly. However, if you carry out 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.

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

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

Examples

# In the public instance, 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.
