Re: [Devil-linux-develop] network configuration script - add routes

[Serge L. <ser...@gm...>]

Hi,

OK, the patch for network script is in the attachment.

If this approach is OK, I'll add 'RULE' keyword to work with additional routing
tables.

The suggest modification of the documentation is below:

########################################################
# ROUTE=" ...... "
# where ROUTE is a key word and the line with ROUTE
# should not have spaces between the beginning of
# the line and the keyword
# and route statement is a any valid "ip route"
# command, without "ip route add" prefix - it will
# be added automatically
#
# IPV6ROUTE="...."
# IPV6ROUTE keyword can be used for ipv6 routes.
#
# $DEVICE can be used to directly specify the interface
#
###### samples for several possible scenarios
#
# route to network 192.168.254.0/255.255.255.0 via gateway 10.90.1.252
#ROUTE="192.168.254.0/255.255.255.0 via 10.90.1.252"
# or
#ROUTE="192.168.254.0/24 via 10.90.1.252"
#
#
# route to host 192.168.3.1 via 10.90.1.252
#ROUTE="192.168.3.0/32 via 10.90.1.252"
#
# route to network that is also reachable via this interface
#ROUTE="192.168.3.0/24 dev $DEVICE"
#
# special routes
#ROUTE="unreachable 10.0.0.0/8"
#ROUTE="blackhole 192.168.1.0/24"
#
# add as many ROUTE="...." lines as you need routes
#
# the next line shows how to set the default gateway
#ROUTE="$default via 10.90.1.1".
#



Sincerely,
Serge
