[LARTC] Three ethernet cards?

[LARTC] Three ethernet cards?

[Jaco van der Schyff]

Hi,

I have a slight problem, is it possible to shape
bandwidth over more than one interface.

I have a linux box with eth0 going to a cisco router,
I want to shape bandwith to eth1 and eth2
eth1 goes to the lan, and eth2 to a DMZ.

How can I accomplish this, so that I can shape
the same bandwith to the DMZ and the lan?
(their bandwith should be shared) ?


                            /eth1 (to local LAN)
                           /
                          /
                         /
          |-------------|
eth0      |             |
-----------             |
to        |             |
internet  |-------------| 
                        \
                         \
                          \
                           \ eth2 (to DMZ)






btw. Thanks for all the help on my previous posts

Just create seperate classes and queueing disciplines for each interface.
And please read the example in the HOWTO, and try to ask more specific
questions.

Ya !! sure it is possible to shape bandwidth on more than one interface. For
e.g. in CBQ whenever u shape bandwidth i.e. when we apply the rules we also
specify to what interface these rules are applied . So for each interface u
have , u specify the bandwidth policy to be applied.

As per my knowledge borrowing bandwidth between cards is not possible as a
seperate Hierarchy would exist for each interface. Within a hierarchy
borrowing/sharing  bandwidth between classes is possible.

iow, It is not possible, to shape the incoming bandwith out to two
networks on sperate NICs?
