Configuring the router alert option on a VLAN
About this task
Use this command to enable the router alert feature. This feature instructs the router to drop
control packets that do not have the router-alert flag in the IP header.

Variable Definitions
Variable
Sets the selected parameter to the default value. If no
parameters are specified, snoop is disabled and all IGMP
parameters are set to their defaults.
Sets the maximum response time (in 1/10 seconds) that
is inserted into group-specific queries sent in response to
leave group messages. This parameter is also the time
between group-specific query messages. This value is
not configurable for IGMPv1.
Decreasing the value reduces the time to detect the loss
of the last member of a group.
The range is from 0–255, and the default is 10 (1 second).
Avaya recommends configuring this parameter to values
higher than 3. If a fast leave process is not required,
Avaya recommends values above 10. (The value 3 is
equal to 0.3 of a second, and 10 is equal to 1.0 second.)
Sets the frequency (in seconds) at which host query
packets are transmitted on the VLAN.
The range is 1–65535. The default value is 125
seconds.
Specifies the maximum response time (in 1/10 seconds)
advertised in IGMPv2 general queries on this interface.
The range is 0–255. The default value is 100 (10
seconds).
Specifies tuning for the expected packet loss of a
network. This value is equal to the number of expected
query packet losses for each serial query interval, plus 1.
If you expect a network to lose query packets, you must
increase the robustness value.
Ensure that the robustness value is the same as the
configured value on the multicast router (IGMP querier).
The range is from 2 to 255, and the default is 2. The
default value of 2 means that one query for each query
interval can be dropped without the querier aging out.
