# Enabling IPv6 Multicast

In this implementation, IPv6 multicast works on VRs. By default, IPv6 multicast is disabled on a VR. To enable IPv6 multicast on a VR, access the context for a VR, and then issue the ipv6 multicast-routing command.

ipv6 multicast-routing

- Use to enable IPv6 multicast routing on the VR.
- By default, IPv6 multicast is disabled on the VR. In the disabled state, all multicast protocols are disabled, and the VR forwards no multicast packets.
- Example
  host1(config)#ipv6 multicast-routing
- Use the no version to disable IPv6 multicast routing on the VR (the default).
- See ipv6 multicast-routing.
