Enhancements to MLD and MLD Snooping (CR00011490)

The following enhancements were made to MLD and MLD Snooping, in accordance with RFC 3810, Multicast Listener Discovery Version 2 (MLDv2) for IPv6.

MLD Packet Formats

MLD messages are now all sent with a hop limit of 1, a link-local source address, and the other format requirements of RFC 3810.

ICMP type for MLDv2 Reports

MLD Report messages now have an ICMP type of 143 by default, as specified by RFC 3810. The previous value was 255.

If you need to maintain backwards compatibility with earlier releases that use an ICMP type of 255, you can do so by using the new v2draftcompat=yes option in the command:

enable ipv6 mld interface=interface v2draftcompat={yesno}

This enables the interface to receive MLDv2 reports with an ICMP type of 255. The default for v2draftcompat is no.

MLD Snooping Group Membership Display

The command show mldsnooping no longer displays the port members of the All Routers group in the list of ports for groups other than the All Routers group. This change makes the output of this command more like output from the command show igmpsnooping.

To illustrate the change, an example of the previous output is shown in Figure 1, and the new output is in Figure 2. In this example, port 9 is in the All Routers group, and is shown in bold.
