Configuring Source Ipv6 Addresses For Mld Messages; Setting The 802.1P Precedence For Mld Messages - HP MSR2003 Configuration Manual

Configuring source IPv6 addresses for MLD messages

You can perform the following configuration to change the source IPv6 address of MLD queries sent by
an MLD snooping querier. You can also change the source IPv6 address of MLD reports or done
messages sent by a simulated member host or an MLD snooping proxy.
Changing the source IPv6 address of MLD queries might affect MLD querier election within the subnet.
To configure the source IP address for MLD queries:
Step
1. Enter system view.
2. Enter VLAN view.
3. Configure the source IPv6
address
queries.
4. Configure the source IPv6
address
multicast-address-specific
queries.
5. Configure the source IPv6
address for MLD reports.
6. Configure the source IPv6
address
messages.

Setting the 802.1p precedence for MLD messages

When congestion occurs on outgoing ports of the Layer 2 device, it forwards MLD messages in their
802.1p priority order, from highest to lowest. You can assign higher forwarding priority to MLD messages
by changing their 802.1p precedence.
You can configure the 802.1p precedence of MLD messages either for the current VLAN in VLAN view
or globally for all VLANs in MLD-snooping view. If the configurations are made in both VLAN view and
MLD-snooping view, the configuration made in VLAN view takes priority.

Remarks

N/A
The default setting is the IPv6
address of the current VLAN
interface. If there is no IPv6
address for the current VLAN
interface, the source IPv6 address
is FE80::02FF:FFFF:FE00:0001.
By default, if the MLD snooping
querier has received MLD general
queries, the source IPv6 address of
MLD multicast-address-specific
queries is the source IPv6 address
of MLD general queries.
Otherwise, it is the IPv6 address of
the current VLAN interface. If there
is no IPv6 address for the current
VLAN interface, it is
FE80::02FF:FFFF:FE00:0001.
The default setting is the IPv6
address of the current VLAN
interface. If there is no IPv6
address for the current VLAN
interface, the source IPv6 address
is FE80::02FF:FFFF:FE00:0001.
The default setting is the IPv6
