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
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

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

Usage guidelines
Execute this command before you use the peer enable command to exchange MDT information with BGP peers or peer groups. MDT information includes the IP address of a PE and the default group to which the PE belongs. On a public network running PIM-SSM, multicast VPN establishes a default MDT rooted at the multicast source-side PE based on the MDT information.
Configurations in BGP IPv4 MDT address family view takes 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

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 PEs 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.
For an MVPN that transmits both IPv4 and IPv6 multicast packets, you must specify the same default group in MVPN IPv4 address family view and MVPN IPv6 address family view.
This command is available only for an MDT-based MVPN.
Examples
# In MVPN IPv4 address family view and MVPN IPv6 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

· 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 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.
advertise-info: Displays advertisement information. If you do not specify this keyword, no advertisement information is displayed.

network-admin
Usage guidelines
Before you execute this command, you must establish BGP VPNv4 peer relationship and BGP IPv4 MVPN neighbor relationship between the device and other devices.
The following BGP extended community attributes are used to identify the route originator of a BGP VPNv4 route:
· Source AS—Carries the number of AS where the MVPN source resides. The format of this attribute is 32-bit AS number:0, for example, 100:0.
· VRF Route Import—Carries the originating address and the VPN instance to which the BGP VPNv4 route belongs. The format of the attribute is 32-bit originating address:VPN instance index, for example, 192.168.122.15:1. The value of the originating address depends on the MVPN source interface configuration.
¡ If the source command is used to specify the MVPN source interface, the originating address is the IP address of the MVPN source interface.
¡ If the source command is not used, the originating address is the router ID of the BGP instance to which the device belongs.

# Allow the device to add Source AS and VRF Route Import extended community attributes to routes sent to the BGP VPNv4 peers.
