| sync zebra routing table with the kernel one when interface is down |
| |
| Add router to kernel main router table with "ip", then you can see |
| a router item in kernel main router table. Also can see this router |
| item in zebra router table. If down the interface, this router item |
| will be deleted from kernel main router table, but it will not be |
| deleted from zebra router table, just set as inactive. |
