Parameters

ipv6-group-address: Specifies an IPv6 multicast group address in the range of FFxy::/16, where "x" and "y" represent any hexadecimal numbers from 0 to F.

prefix-length: Specifies the address prefix length in the range of 8 to 128.

all: Specifies all IPv6 multicast boundaries configured on the interface.

scope-id: Specifies the ID of an admin-scoped zone, in the range of 3 to 15, which is identified by the scope field in the IPv6 multicast group address.

admin-local: Specifies the scoped zone as admin-local, which has a scope ID of 4.

global: Specifies the scoped zone as global, which has a scope ID of 14.

organization-local: Specifies the scoped zone as organization-local, which has a scope ID of 8.

site-local: Specifies the scoped zone as site-local, which has a scope ID of 5.

Usage guidelines

A multicast forwarding boundary sets the boundary condition for the IPv6 multicast groups in the specified address range. If the destination address of an IPv6 multicast packet matches the set boundary condition, the packet is not forwarded.

An interface can act as a forwarding boundary for multiple IPv6 multicast groups in different address ranges. You can implement this by using this command on the interface for each multicast address range. These multicast groups must be in the same scope. The latest configuration of a scope overwrites the previous one.

You do not need to enable IPv6 multicast routing before you execute this command.

Assume that Set A and Set B are both IPv6 multicast forwarding boundary sets with different address ranges, and that B is a subset of A. A takes effect on the interface no matter whether A is configured earlier or later than B.

This configuration does not affect users that come online through an interface configured with IPv6 multicast access control. Such users can still join IPv6 multicast groups specified for the multicast forwarding boundary.

Examples

# Configure Ten-GigabitEthernet 3/0/1 as the forwarding boundary of IPv6 multicast groups in the range of FF03::/16.

per-entry-limit: Specifies the maximum number of unknown IPv6 multicast packets that can be cached for an (S, G) entry. The value range for this argument is 0 to 256. If you set the value to 0, the device cannot cache unknown IPv6 multicast packets.

Examples

# Set the maximum number to 20 for unknown IPv6 multicast packets that can be cached for an (S, G) entry.

<Sysname> system-view

[Sysname] ipv6 multicast forwarding-table cache-unknown per-entry 20

Related commands

ipv6 multicast forwarding-table cache-unknown total

Use ipv6 multicast forwarding-table cache-unknown total to set the maximum number of all unknown IPv6 multicast packets that can be cached.

Use undo multicast forwarding-table cache-unknown total to restore the default.

Syntax

ipv6 multicast forwarding-table cache-unknown total total-limit

undo ipv6 multicast forwarding-table cache-unknown total

Default

The device can cache 1024 unknown IPv6 multicast packets in total.

Parameters

total-limit: Specifies the maximum number of all unknown IPv6 multicast packets that can be cached. The value range for this argument is 0 to 65535. If you set the value to 0, the device cannot cache unknown IPv6 multicast packets.

Usage guidelines

As a best practice, set the value in this command to be far greater than the value set in the ipv6 multicast forwarding-table cache-unknown per-entry command.

Examples

# Set the maximum number to 10000 for all unknown IPv6 multicast packets that can be cached.

undo ipv6 multicast frr mode

Default

The IPv6 multicast FRR mode is by-entry.

Views

System view

Predefined user roles

network-admin

Parameters

by-entry: Specifies the by-entry mode. In this mode, IPv6 multicast FRR periodically monitors IPv6 multicast traffic on primary and backup incoming interfaces by entry.

by-iif: Specifies the by-incoming interface mode. In this mode, IPv6 multicast FRR periodically monitors IPv6 multicast traffic for different (S, G) entries by pair of primary and backup incoming interfaces.

Usage guidelines

With IPv6 multicast FRR enabled, the device will add a primary incoming interface and a backup incoming interface for each (S, G) entry and (*, G) entry during entry creation. It will periodically monitor IPv6 multicast traffic on the primary and backup incoming interfaces of all entries. If no IPv6 multicast traffic is detected on the primary incoming interface, the device determines that the primary incoming interface fails and uses the backup incoming interface for IPv6 multicast forwarding.

As a best practice, set the IPv6 multicast FRR mode to by-incoming interface if the device has a large number of IPv6 multicast entries and most entries have the same primary and backup incoming interfaces.

In the current software version, only IPv6 PIM supports multicast FRR. For more information about IPv6 PIM FRR, see PIM configuration in IP Multicast Configuration Guide.

Predefined user roles

network-admin

Parameters

monitor-time: Specifies the primary/backup link monitoring interval in milliseconds. Valid values are 10, 20, 40, 100, 200, and 500.

Usage guidelines

Before executing this command, execute the rpf-frr enable or c-multicast frr command to enable PIM FRR or MVPN FRR.

With IPv6 multicast FRR enabled, the device will add a primary incoming interface and a backup incoming interface for each (S, G) entry and (*, G) entry during entry creation. It will periodically monitor multicast traffic on the primary and backup incoming interfaces of all entries. If no multicast traffic is detected on the primary incoming interface, the device determines that the primary incoming interface fails and uses the backup incoming interface for multicast forwarding. You can set the internal at which multicast FRR monitors the states of the primary and backup links.

As a best practice to prevent the CPU from being overloaded, set the monitoring interval to a larger value if there are many multicast entries. As a best practice to prevent the device from determining link failures mistakenly when the multicast traffic rate is small, also set the monitoring interval to a larger value if there are many multicast entries.

undo ipv6 multicast frr wtr

Default

Traffic switchback is disabled and the wait-to-restore (WTR) time is 60 seconds.

Views

System view

Predefined user roles

network-admin

Parameters

wtr-time: Specifies the wait-to-restore (WTR) time in the range of 60 to 1800 seconds.

disable: Disables traffic switchback.

Usage guidelines

Before executing this command, execute the rpf-frr enable or c-multicast frr command to enable PIM FRR or MVPN FRR.

To prevent multicast traffic from being switched back before the multicast entries are created for the primary link, do not set too short a wait-to-restore (WTR) time.

Multicast packets might be lost or duplicate multicast packets might exist during a traffic switchback. As a best practice, do not configure traffic switchback for multicast services requiring high reliability.

Examples

# Set the WTR time to 800 seconds.

Syntax

ipv6 multicast global limit pim sm { star-group-number | source-group-number } limit-count [ alarm-threshold upper-limit upper-limit lower-limit lower-limit ]

undo ipv6 multicast global limit pim sm { star-group-number | source-group-number }

Default

The number of IPv6 PIM entries is not limited.

Views

System view

Predefined user roles

network-admin

Parameters

star-group-number: Limits the number of IPv6 (*,G) entries.

source-group-number: Limits the number of IPv6 (S,G) entries.

limit-count: Specifies the maximum number of IPv6 PIM entries allowed, in the range of 1 to 16384.

alarm-threshold upper-limit upper-limit: Specifies the upper limit of IPv6 PIM entries that causes a log message to be generated. The upper-limit argument specifies a percentage of the maximum number of IPv6 PIM entries allowed. The default is 80. As a best practice, do not configure a value greater than 95.

alarm-threshold lower-limit lower-limit: Specifies the lower limit of IPv6 PIM entries that causes a log message to be generated. The lower-limit argument specifies a percentage of the maximum number of IPv6 PIM entries allowed. The default is 70. The value for the lower-limit argument must be smaller than or equal to the value for the upper-limit argument. As a best practice to avoid generating log messages frequently, do not configure a value smaller than 10.

Usage guidelines

When an illegal user launches an attack by using multicast data or protocol (MLD or IPv6 PIM) packets, a large number of multicast routing entries might be generated, causing high memory or CPU usage. This command can protect the device by limiting the number of MLD or IPv6 PIM entries.

When the number of global MLD or IPv6 PIM entries reaches the limit, new MLD or IPv6 PIM entries cannot be created and a log message is generated. The log messages are sent to the information center for processing. With the information center, you can set log message filtering and output rules, including output destinations. For more information about the information center, see Network Management and Monitoring Configuration Guide.

Static (*,G) entries, static (S,G) entries, and ASM default group entries are not affected by this function.

Examples

# Set the maximum number of IPv6 (S,G) entries allowed to 1000.

<Sysname> system-view

[Sysname] ipv6 multicast global limit pim sm source-group-number 1000

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command configures a static IPv6 multicast route on the public network.

ipv6-source-address: Specifies an IPv6 multicast source address.

prefix-length: Specifies the address prefix length in the range of 0 to 128. The default is 128.

ipv6-rpf-nbr-address: Specifies an RPF neighbor by its IPv6 address.

interface-type interface-number: Specifies an interface by its type and number. The interface connects the RPF neighbor.

preference: Sets a route preference in the range of 1 to 255. The default is 1.

description text : Specifies the description of the static IPv6 multicast route, a case-sensitive string of 1 to 60 characters. The description can include blank spaces and special characters except for the question mark (?).

Usage guidelines

If the interface connected to an RPF neighbor is a point-to-point interface, you must specify the interface by its type and number.

If the interface connected to an RPF neighbor is not a point-to-point interface, you must specify the interface by its IP address. This type of interfaces includes Layer 3 Ethernet, Layer 3 aggregate, loopback, and VLAN interfaces.

The configured static IPv6 multicast route might not take effect when one of the following conditions exists:

· The outgoing interface iteration fails.

· The specified interface is not in the public network or the same VPN instance as the current interface.

· The specified interface is not a point-to-point interface.

· The specified interface is down.

If multiple static IPv6 multicast routes within the same IPv6 multicast source address range are available, only the one with the highest route preference can become active. You can use the display ipv6 multicast routing-table static command to verify that the configured static IPv6 multicast route has taken effect.

The undo ipv6 rpf-route-static command deletes the specified static IPv6 multicast route. To delete all static IPv6 multicast routes, use the delete ipv6 rpf-route-static command.

Examples

# Configure a static IPv6 multicast route to IPv6 multicast source 101::0/64 and specify the interface with IP address 106::7 as the RPF neighbor on the public network.

Default

Load splitting of IPv6 multicast traffic is disabled.

Views

IPv6 MRIB view

Predefined user roles

network-admin

Parameters

balance-ecmp: Enables IPv6 multicast load balancing based on ECMP paths. Multicast traffic is evenly distributed among ECMP paths.

balance-ucmp: Enables IPv6 multicast load balancing based on links. Multicast traffic is evenly distributed among links.

ecmp: Enables IPv6 multicast load splitting based on ECMP paths.

source: Enables IPv6 multicast load splitting based on IPv6 multicast sources.

source-group: Enables IPv6 multicast load splitting based on IPv6 multicast sources and groups.

ucmp: Enables IPv6 multicast load splitting based on links.

Usage guidelines

On a network with ECMP routes, specify the balance-ecmp, ecmp, source, or source-group keyword. On a network with UCMP routes, specify the balance-ucmp or ucmp keyword.

· If you specify the ecmp keyword, adding or deleting ECMP routes severely affects IPv6 multicast forwarding.

· If you specify the source or source-group keyword, adding or deleting ECMP routes slightly affects IPv6 multicast forwarding. Specify either of the keywords on a network with unstable equal cost links.

· If you specify the balance-ecmp or balance-ucmp keyword, the device uses a polling mechanism for IPv6 multicast load balancing. ECMP or UCMP-based IPv6 multicast load balancing provides better stability and balance than ECMP or UCMP-based IPv6 multicast load sharing.
