The undo send-router-alert command globally specifies that the IGMP packet sent by a FW does not contain the Router-Alert option in its IP packet header.

Format

send-router-alert

undo send-router-alert

Parameters

None

Views

IGMP view

Default Level

2: Configuration level

Usage Guidelines

By default, the IGMP packet sent by the FW contains the Router-Alert option in its IP packet header.

The function of this command is the same as that of the igmp send-router-alert used in the interface view, except for the function range. The configuration in the IGMP view is globally valid in the instance, whereas the configuration in the interface view is valid only for the current interface. The system prefers the configuration in the system view. The configuration in the IGMP view is used only when the configuration in the interface view is not done.

Example

# In the IGMP view, specify that the IGMP packet sent by the FW does not contain the Router-Alert option in its IP packet header.
