[PATCH] Zebra rib/fib to be in sinc with kernel routing table
|
|
From: Igor Maravic <igorm [at] etf>
Enable Zebra rib/fib to be in sinc with kernel routing table. That means
when interface goes down, all routes that are directly connected to it are
deleted from Zebra's rib/fib just like they are delete from kernel
routing table.
