From 8dcf042a7f58dfac590b28174dc1d9b87ce5a893 Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Sat, 4 Apr 2020 13:46:38 +0200 Subject: pppoe: T2219: move adding of default route to ip-(up|down) script As PPPoE interfaces should be part of a VRF it is required that the default can also be set into the specified VRF. The default way of PPP by setting the "defaultroute" option does not take a VRF into account. In this case PPP installs a Kernel route forwarding all default traffic over this interface. This change installs a static route with metric 1 instead into the routing table via FRR. This is not the same as a Kernel route in terms of metric 1 compared to 0 but it should do the trick. --- data/templates/pppoe/ip-down.script.tmpl | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 data/templates/pppoe/ip-down.script.tmpl (limited to 'data/templates/pppoe/ip-down.script.tmpl') diff --git a/data/templates/pppoe/ip-down.script.tmpl b/data/templates/pppoe/ip-down.script.tmpl new file mode 100644 index 000000000..f90da02bc --- /dev/null +++ b/data/templates/pppoe/ip-down.script.tmpl @@ -0,0 +1,16 @@ +#!/bin/sh + +# As PPPoE is an "on demand" interface we need to re-configure it when it +# becomes up + +if [ "$6" != "{{ intf }}" ]; then + exit +fi + +# add some info to syslog +DIALER_PID=$(cat /var/run/{{ intf }}.pid) +logger -t pppd[$DIALER_PID] "executing $0" + +# Debian PPP version has no support for replacing an existing default route +# thus we emulate this ba an ip-up script https://phabricator.vyos.net/T2220. +vtysh -c "conf t" -c "no ip route 0.0.0.0/0 {{ intf }}" -- cgit v1.2.3
