The ipv6 route-static track bfd-session admindown invalid command prevents an IPv6 static route from being selected if the BFD session associated with it is in the AdminDown state.
The undo ipv6 route-static track bfd-session admindown invalid command restores the default configuration.
By default, an IPv6 static route can still be selected by the FW even though the BFD session associated with it is in the AdminDown state.
ipv6 route-static track bfd-session session-name bfd-name admindown invalid
undo ipv6 route-static track bfd-session [ session-name bfd-name ] admindown invalid
| Parameter | Description | Value |
|---|---|---|
session-name bfd-name |
Specifies a BFD session bound to an IPv6 static route. |
The value is a string of 1 to 15 case-insensitive characters, spaces not supported. NOTE:
When double quotation marks are used around the string, spaces are allowed in the string. |
Usage Scenario
By default, an IPv6 static route can still be selected by the FW even though the BFD session associated with it is in the AdminDown state, but not by non-Huawei devices. As a result, the FW cannot interwork with non-Huawei devices.
To address this problem, run the ipv6 route-static track bfd-session admindown invalid command to configure the FW not to select the IPv6 static route if the BFD session associated with it is in the AdminDown state.
Prerequisites
The BFD session specified by bfd-name has been created.
Precautions
The undo ipv6 route-static track bfd-session admindown invalid command enables all IPv6 static routes to be selected by the FW even though the BFD sessions associated with them are in the AdminDown state.
# Prevent the IPv6 static route from being selected if the BFD session associated with it is in the AdminDown state.
