Multicast Listener Discovery (MLD) Snooping
Configuring MLD
Configuring Per-Port MLD Traffic Filters
For example:
Figure 7-3. Example of an MLD Configuration with Traffic Filters
Syntax: ipv6 mld [auto <port-list> | blocked <port-list> | forward <port-list>]
Note: This command must be issued in a VLAN context.
This command sets per-port traffic filters, which specify how
each port should handle MLD traffic. Allowed settings are:
auto—follows MLD snooping rules: packets are forwarded for
joined groups
blocked—all multicast packets are dropped, except that packets
for well known addresses are forwarded
forward—all multicast packets are forwarded
The default value of the filter is auto.
<port-list>—specifies the affected port or range of ports
ProCurve(vlan-8)# ipv6 mld forward a16-a18
ProCurve(vlan-8)# ipv6 mld blocked a19-a21
ProCurve(vlan-8)# show ipv6 mld vlan 8 config
