what are the iproute2 rules and routes startup scripts

[Robin Mordasiewicz]

How do I configure iproute2 rules and route tables to automatically start 
at boot time, or to be run when the network script is run

ie. I can issue the following commands, but when the machine reboots the 
settings are not automtically set. Typically I have been accustomed to 
editing /etc/sysconfig/network to establist a default route, but I need to 
configure multiple routing tables. I can edit /etc/iproute2/rt_tables to 
add the table names, but where do I put the config settings for the rules 
and routes.


[root@localhost]# ip route add default via 10.90.2.1 dev bond0.902 table 11
[root@localhost]# ip ru add from 10.90.2.244/32 table 11 priority 500

device specific routes: /etc/sysconfig/network-scripts/route-<device>

device independent routes:
/etc/sysconfig/static-routes

Both take "ip route" syntax, only "static-routes" requires a leading
"any" for each line. See /usr/share/doc/initscripts-*/sysconfig.txt for
more.

Ok, but what about the rules,
ie. When issueing the following commands I understand how I can use the 
route-device file, but which file do edit to deal with the "ip rule add" 
line ?

/sbin/ip rule delete from ${IPADDR} lookup ${TABLE}
/sbin/ip rule add from ${IPADDR} table ${TABLE} priority ${PRIORITY}

If you are willing to do some packaging work, you might want to look
at /etc/net, which has been developed for the ALTLinux distribution:

   http://etcnet.org/

   /etc/net represents a new approach to Linux network configuration
   tasks. Inspired by the limitations of traditional configuration
   subsystems, /etc/net provides builtin support for:

       * configuration profiles
       * interface name management
       * removable devices
       * full iproute2 command set
       * interface dependencies resolution
       * QoS configuration framework
       * firewall support

   /etc/net provides support for the following interface types:

       * Ethernet
       * WiFi (WEP)
       * IPv4/IPv6 tunnels
       * PSK IPSec tunnels
       * VLAN
       * PLIP
       * Ethernet bonding and bridging
       * traffic equalizer
       * usbnet
       * PPP (PPtP, PPPoE)
       * DVB (SkyStar-2, Pent@NET, Pent@VALUE)

   Due to its modular design, support for new interface types can be added
   without overall design changes. /etc/net consists of core scripts (stable)
   and GUI configurator (development). Both parts are licensed under GPL.
   
To get this packaged properly under Fedora, you'll want to hack up the
initscripts package spec file to split off the networking parts into a
subpackage (call it netscripts or whatever) and then package up etcnet as a
replacement.  I filed an RFE for subpackage separation a while ago,
but Buill Nottingham nixed the idea:

That looks interesting, but I don't have any time for development on this. 
I need something that "Just Works".

What I have done is written a script in /sbin/ifup-local, which will add 
the rules I need. I don't like it, but it will get me by. I think that in 
the long run the /etc/net approach will be a better strategy, but for now 
I need somehting which is also supported by RedHat-AS
