Enabling Multicast Routing for a VPN Instance

Enabling Multicast Routing for a VPN Instance

Context

You must enable IP multicast routing for a VPN instance before configuring multicast protocols. Other multicast functions can be configured only after IP multicast routing is enabled. All multicast configurations become invalid when IP multicast routing is disabled.

Perform the following steps on a PE.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    ip vpn-instance vpn-instance-name

    The VPN instance view is displayed.

    The vpn-instance-name parameter specifies the name of the VPN instance that has been deployed on the PE and requires multicast data forwarding. For the VPN configuration, see BGP/MPLS IP VPN Configuration in the S7700 and S9700 V200R010C00 Configuration Guide - VPN.

  3. (Optional) Run:

    ipv4-family

    The IPv4 address family is enabled for the VPN instance, and the VPN instance IPv4 address family view is displayed.

    By default, the VPN instance IPv4 address family is enabled after a route distinguisher (RD) is configured for VPN instance using the route-distinguisher command in the VPN instance view.

  4. Run:

    multicast routing-enable

    IP multicast routing is enabled for the VPN instance.

    By default, IP multicast routing is disabled for a VPN instance
