From 012d20eebe3aec0818aa949eb7b14754640df797 Mon Sep 17 00:00:00 2001 From: Mogula Pranay Date: Tue, 9 Jan 2018 11:43:29 +0530 Subject: [PATCH] netifd: update dhcp.script to handle dynamic routing Certain DHCP servers push a gateway outside of the assigned interface subnet, to support those situations, install a host route towards the gateway. If Gateway and IP are served in same network, openwrt quagga cannot learn routes (rip routes are not getting added, showing inactive) whereas working fine when Gateway and IP are in different network.
