From 22e8e589fd6ab5d19dc1d3c9d1bcf2bfabf1fafb Mon Sep 17 00:00:00 2001 From: Hans Dedecker Date: Fri, 17 May 2019 18:27:59 +0200 Subject: [PATCH] interface-ip: use ptp address as well to find local address target In case of tunnel over PPP(such as gretap over l2tp): tunnel interface use PPP's peer address as remote address, netifd script will call proto_add_host_dependency function, then netifd will search which device can reach to the remote address. Before the patch, netifd don't consider the PPP interface can reach to the remote address, so netifd will select default route to remote address, it will lead to remote address unreachable.
