>Description:
'link1' flag doesn't work as intended when configured for gre tunnel using main system config files:
- when configured via ifconfig_gre0="" with all appropriate parameters the interface does appear with 'LINK1' flag, but requires an additional 'ifconfig gre link1' command for the tunnel to start working;
- when configured via 'start_if.gre0' script with all additional parameters, for example
===Cut===
#!/bin/sh
/sbin/ifconfig gre0 192.168.1.1 192.168.1.2 netmask 255.255.255.255 10.10.10.1 10.10.10.5 mtu 1480
# even when sleep 10
sleep 10
/sbin/ifconfig gre0 link1
===Cut==
the system still requires 'ifconfig gre0 link1' for the tunnel to start working;
>How-To-Repeat:
Create a gre tunnel with link1 set in configuration files; in rc.conf or even in start_if.gre0.
Reboot the machine.
Try to ping remote.
>Fix:
echo gre_enable="YES" >> /etc/rc.conf
echo gre_flags="greX link1" >> /etc/rc.conf
(according to your configuration)
and place the following script to /usr/local/etc/rc.d/:
#!/bin/sh
#
#
# gre startup script by drookie, 14/04/2007 12:38
# to avoid link1 bug when it is configured in earlier scripts :/
#
# PROVIDE: gre
# REQUIRE: LOGIN NETWORKING
#
#
name=gre
command=/sbin/ifconfig
gre_enable=${gre_enable:-"NO"}
. /etc/rc.subr
rcvar=`set_rcvar`
load_rc_config ${name}
run_rc_command "$1"
