disable iproute bfd strict
Description
Turns off "strict" Bidirectional Forwarding Detection (BFD) session control, which brings up the static route during switch reboot if the static route nexthop BFD session is in the INIT state.
Syntax Description
| protection | Enables or disables route protection. |
| bfd | BFD protect static routes to next hop gateway. |
| strict | Disables considering that protected static routes are not up if the BFD session is in INIT state. Default is disabled. |
Default
By default, strict BFD session control is disabled.
Usage Guidelines
If the BFD session is down, but BFD protected static route is still in the routing table after reboot, the BFD session is never established, because during reboot, the BFD session is in the INIT state, and the static route is brought up without considering BFD session state. This can cause traffic loss because the link to the gateway actually is down. This command turns off strict BFD session control, which means that the static route is brought up during reboot even if the BFD session is in the INIT state. A reboot is required to make the command take effect.
Example
The following example disables BFD strict session control:
# disable iproute bfd strict WARNING: Please reboot the switch for the strict BFD to take effect.
