When any one of the timers decreases to 0, the host will group member announce
messages.Configuring the maximum response time reasonablely,the host can swiftly
response to the query messages and the router can also get the group members’ existing
states quickly.
Example:
Configure the maximum response time of MLD queries to 20s
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ipv6 mld query- max-response-time 20
18.3.3.6 ipv6 mld query-timeout
Command: ipv6 mld query-timeout <time_val>
no ipv6 mld query-timeout
Function:
Configure the interface’s timeout of MLD queries; the “
no ipv6 mld
query-timeout
” command
restores the default value
Parameter: <time_val>
is the timeout of MLD queries, it ranges from 60 to 300s
Default:
Default: 255s
Command Mode:
Interface Configuration Mode
Usage Guide:
In the share network,when there are more switches that run MLD,one
switch will be selected as the querying host and others set a timer to inspect the querying
host’s state. If no querying packet is received when the timeout is over, a switch wiil be
reselected as the querying host .
Example:
Configure the interface’s timeout of MLD queries to 100s
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ipv6 mld query-timeout 100
18.3.3.7 ipv6 mld access-group
Command: ipv6
mld
access-group {<acl_name>}
no ipv6 mld access-group
Function:
Configure the filter conditions of the interface on the MLD group; the “
no ipv6
mld access-group
” ommand cancels the filter conditions.
Parameter: <acl-name>
is the name of the IPv6 access list
Default:
No filter condition by default
Command Mode:
Interface Mode
Usage Guide:
This command can configure the filter on the interface to the groups,
permitting or denying certain groups.
Example:
Configure the interface vlan1 to permit group FF1E::1:0/112, while denying all
others.
Switch (Config)# ipv6 access-list aclv6 permit FF1E::1:0/112
Switch (Config)# ipv6 access-list aclv6 deny any
