Multicast VPN commands

address-family ipv4

Use address-family ipv4 to create an MVPN IPv4 address family and enter its view, or enter the view of the existing MVPN IPv4 address family.

Use undo address-family ipv4 to delete the MVPN IPv4 address family and configurations in MVPN IPv4 address family view.

Syntax

address-family ipv4

undo address-family ipv4

Default

No MVPN IPv4 address family exists.

Views

MVPN view

Predefined user roles

network-admin

mdc-admin

Usage guidelines

Configurations in MVPN IPv4 address family view of a VPN instance apply only to IPv4 multicast packets of that instance.

Examples

# In MVPN view of VPN instance mvpn, create an MVPN IPv4 address family and enter its view.

<Sysname> system-view

[Sysname] multicast-vpn vpn-instance mvpn mode mdt

[Sysname-mvpn-mvpn] address-family ipv4

[Sysname-mvpn-mvpn-ipv4]

address-family ipv4 mdt

Use address-family ipv4 mdt to create a BGP IPv4 MDT address family and enter its view, or enter the view of the existing BGP IPv4 MDT address family.

Use undo address-family ipv4 mdt to delete the BGP IPv4 MDT address family and all configurations in BGP IPv4 MDT address family view.

Syntax

address-family ipv4 mdt

undo address-family ipv4 mdt

Default

No BGP IPv4 MDT address family exists.

Views

BGP instance view

Predefined user roles

network-admin

mdc-admin

Usage guidelines

Execute this command before you use the peer enable command to enable BGP peers to exchange MDT information. MDT information includes the IP address of a PE device and the default group to which the PE device belongs. On a public network running PIM-SSM, multicast VPN establishes a default MDT rooted at the PE device (multicast source) based on the MDT information.

Configurations in BGP IPv4 MDT address family view take effect only on BGP MDT messages, BGP MDT peers, and BGP MDT peer groups.

Examples

# In BGP instance view of BGP instance default, create a BGP IPv4 MDT address family and enter its view.

<Sysname> system-view

[Sysname] bgp 100

[Sysname-bgp-default] address-family ipv4 mdt

[Sysname-bgp-default-mdt]

# In BGP instance view of BGP instance abc, create a BGP IPv4 MDT address family and enter its view.

<Sysname> system-view

[Sysname] bgp 100 instance abc

[Sysname-bgp-abc] address-family ipv4 mdt

[Sysname-bgp-abc-mdt]

Related commands

peer enable (see Layer 3—IP Routing Command Reference)

data-delay

Use data-delay to set the data-delay period (delay period before the device switches over from the default MDT to the data MDT).

Use undo data-delay to restore the default.

Syntax

data-delay delay

undo data-delay

Default

The data-delay period is 3 seconds.

network-admin

mdc-admin

Parameters

delay: Specifies a data-delay period in the range of 1 to 60 seconds.

Usage guidelines

This command is available only for an MDT-based MVPN.

Examples

# In MVPN IPv4 address family view of VPN instance mvpn, set the data-delay period to 20 seconds.

<Sysname> system-view

[Sysname] multicast-vpn vpn-instance mvpn mode mdt

[Sysname-mvpn-mvpn] address-family ipv4

[Sysname-mvpn-mvpn-ipv4] data-delay 20

data-group

Use data-group to specify a data group range and optionally configure the criteria for the device to initiate a switchover of the default MDT to a data MDT.

Use undo data-group to restore the default.

Syntax

data-group group-address { mask-length | mask } [ acl acl-number]

undo data-group

Default

No data group range exists, and the device never initiates a switchover of the default MDT to a data MDT.

Parameters

group-address: Specifies a multicast group address in the range of 224.0.1.0 to 239.255.255.255.

mask-length: Specifies a mask length for the multicast group address. The value range for this argument is 24 to 32.

mask: Specifies a subnet mask for the multicast group address. The value range for this argument is 255.255.255.x, where x can be only 0, 128, 192, 224, 240, 248, 252, 254, or 255.

acl acl-number: Specifies an advanced ACL by its number in the range of 3000 to 3999. If you specify an ACL, the multicast data permitted by the ACL can trigger the switchover. If you do not specify an ACL, any multicast data can trigger the switchover. For the ACL to take effect, specify the protocol type as IP, and include the source and destination keywords when you create an ACL rule. The source and destination keywords specify a multicast source address range and a multicast group address range, respectively.

Usage guidelines

On a PE, the data group range for an MVPN cannot include the default group or data groups of any other MVPN.

All VPN instances share the data group resources. As a best practice to avoid data group resource exhaustion, specify a reasonable data group range for a VPN instance.

The data group ranges for different MDs on different PE devices cannot overlap with one another if the PIM mode is not PIM-SSM on the public network.

If you execute this command multiple times in the same MVPN IPv4 address family view, the most recent configuration takes effect.

This command is available only for an MDT-based MVPN.

Examples

# In MVPN IPv4 address family view of VPN instance mvpn, specify 239.1.2.0 through 239.1.2.255 as the data group range.

<Sysname> system-view

[Sysname] multicast-vpn vpn-instance mvpn mode mdt

[Sysname-mvpn-mvpn] address-family ipv4

[Sysname-mvpn-mvpn-ipv4] data-group 239.1.2.0 24

default-group

Use default-group to specify a default group.

Use undo default-group to restore the default.

Syntax

default-group group-address

undo default-group

Default

No default group exists.

Parameters

group-address: Specifies a default group in the range of 224.0.1.0 to 239.255.255.255.

Usage guidelines

You must specify the same default group on all PE devices that belong to the same MVPN.

The default group for an MVPN must be different from the default group and the data group used by any other MVPN.

This command is available only for an MDT-based MVPN.

Examples

# In MVPN IPv4 address family view of VPN instance mvpn, specify 239.1.1.1 as the default group.

<Sysname> system-view

[Sysname] multicast-vpn vpn-instance mvpn mode mdt

[Sysname-mvpn-mvpn] address-family ipv4

[Sysname-mvpn-mvpn-ipv4] default-group 239.1.1.1

[Sysname-mvpn-mvpn-ipv4] quit

·     32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.

·     32-bit AS number:16-bit user-defined number, where the AS number must be equal to or greater than 65536. For example, 65536:1.

ip-address: Specifies a multicast source by its IP address. The ip-address argument represents the IP address of the PE device in the default MDT. If you do not specify a multicast source, this command displays brief information about BGP MDT routes for all multicast sources.

Usage guidelines

This feature enables PE devices to carry the RPF vector information in PIM join messages for other devices to perform RPF check on the messages.

You must enable this feature on PE devices (excluding the PE devices that do not have attached receivers) when you configure multicast VPN inter-AS option B.

Only the configuration made in MRIB view of a VPN instance takes effect. The configuration made in MRIB view on the public network does not take effect.

This command is available only for an MDT-based MVPN.

Examples

# Enable the RPF vector feature for VPN instance mvpn.
