acl6-number: Basic IPv6 ACL number. When an IPv6 ACL is defined, the source keyword in the rule command specifies a legal BSR source IPv6 address range.

Description

Use the bsr-policy command to configure a legal range of BSR global unicast addresses so that the device discards any bootstrap messages from out of the configured address range to guard against BSR spoofing.

Use the undo bsr-policy command to remove the restore the system default.

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

Examples

# Configure a legal BSR address range so that only routers with an address in the range of 2001::2/64 can become the BSR.

Parameters

interval: Bootstrap timeout in seconds.

Description

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

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

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

& Note:

The default bootstrap interval is 60 seconds, so the default bootstrap timeout = 60 × 2 + 10 = 130 (seconds).

Related commands: c-bsr, c-bsr interval.

Examples

# Set the bootstrap timeout time to 150 seconds.

Parameters

interval: Bootstrap interval in seconds.

Description

Use the c-bsr interval command to configure the bootstrap interval, namely the interval the BSR waits between sending bootstrap messages.

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

By default, the bootstrap interval value is determined by this formula: Bootstrap interval = (Bootstrap timeout – 10) / 2.

& Note:

The default bootstrap timeout is 130 seconds, so the default bootstrap interval = (130 – 10) / 2 = 60 (seconds).

Related commands: c-bsr, c-bsr holdtime.

View

IPv6 PIM view

Default Level

2: System level

Parameters

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

acl6-number: Basic IPv6 ACL number. 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.

priority: Priority of the C-RP, 0 by default. A larger value means a lower priority.

hold-interval: C-RP timeout time, in seconds. 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. If you do not include this argument in your command, the corresponding global setting will be used.

Description

Use the c-rp command to configure the specified interface 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 Note that any interface serving as a C-RP must be IPv6 PIM-SM enabled.

l If you do not specify an IPv6 multicast group range for the C-RP, the C-RP will serve all IPv6 multicast groups.

l If you wish a device 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.

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.

Description

Use the c-rp holdtime command to configure globally the C-RP timeout time, namely the length of time the BSR waits before it must receive a C-RP-Adv message from a C-RP.

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, the C-RP timeout time should be longer than the bootstrap interval. The recommended C-RP timeout setting is 2.5 times the bootstrap interval or longer.

Related commands: c-rp, c-bsr interval.

Examples

# Set the global C-RP timeout time to 200 seconds.

acl6-number: Advanced IPv6 ACL number. When configuring the IPv6 ACL, use the source keyword in the rule command to specify the IPv6 address of a C-RP and the destination keyword to specify the 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 restore the system default.

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.

1.1.20 display pim ipv6 rp-info

Syntax

display pim ipv6 rp-info [ ipv6-group-address ]

View

Any view

Default Level

1: Monitor level

Parameters

ipv6-group-address: Specifies an IPv6 multicast group. If you do not provide a group address, this command will display the RP information corresponding to all IPv6 multicast groups.

Description

Use the display pim ipv6 rp-info command to view the RP information.

Note that:

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 IPv6 multicast group FF0E::101:101.

<Sysname> display pim ipv6 rp-info ff0e::101:101

PIM-SM BSR RP information:

View

IPv6 PIM view

Default Level

1: Monitor level

Parameters

acl6-number: Advanced IPv6 ACL number. Only those register messages that match the permit statement of the IPv6 ACL can be accepted by the RP.

Description

Use the register-policy command to configure an IPv6 ACL rule to filter register messages.

Use the undo register-policy command to remove the configured register filtering rule.

By default, no register filtering rule is configured.

Within an IPv6 PIM-SM domain, the DR sends register messages with different source/group addresses to the RP. You can configure a filtering rule to accept or reject certain register messages so that the RP can serve specific IPv6 multicast groups.

If an (S, G) entry is denied by the ACL, or the action for this entry is not defined, the RP will send a register-stop message to the DR to stop the registration process for the multicast stream.

Caution:

The RP will reject all register messages if you specify an IPv6 advanced ACL without a rule definition.

Examples

# Configure a register filtering policy on the RP so that only IPv6 multicast sources on the subnet 3:1::/64 can send register messages to the IPv6 multicast groups on the subnet FF35:13::/64.

1.1.48 register-suppression-timeout

Syntax

register-suppression-timeout interval

undo register-suppression-timeout

View

Default Level

2: System level

Parameters

interval: Register suppression timeout in seconds.

Description

Use the register-suppression-timeout command to configure the register suppression timeout time.

Use the undo register-suppression-timeout command to restore the system default.

By default, the register suppression timeout time is 60 seconds.

Note that:

l When a device, as a DR, receives an (S, G)-specific register-stop message from the RP, the device immediately stops sending register messages with encapsulated multicast data and enters the register suppression state.

l A smaller timeout setting causes bursts of multicast data to flow to the RP more frequently, and a larger timeout setting results in a larger delay for new receivers to join a multicast group.

l Defining a probe time setting in the probe-interval command reduces bursts of register messages, and a appropriately reduced setting of the suppression timeout time reduces the delay for new receivers to join a multicast group.

Related commands: probe-interval.

Parameters

acl6-number: Basic or advanced IPv6 ACL number.

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.

Note that:

l If you specify a basic ACL, the device filters the received IPv6 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 the received IPv6 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.

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

group-policy acl6-number: Specifies an IPv6 group policy. RPT-to-SPT switchover will be disabled for IPv6 multicast groups that match the specified group policy. In this option, acl6-number refers to 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 disable RPT-to-SPT switchover.

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

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

Note that:

l 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.

l 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.

l If you use this command multiple times on the same IPv6 multicast group, the first traffic rate configuration matched in sequence will take effect.

l To avoid forwarding failure, do not include the infinity keyword in the spt-switch-threshold command on a switch that may become an RP (namely, a static RP or a C-RP).
