[mpls-linux-general] the quesion about traffic balancing

[Folke A. <aeo...@ho...>]

hi, all :)

   i got a problem in balancing my traffic through
my network.

   see the following network topology:
      +------+      +------+     +------+   |
      |      |eth1  |      |     |      |   |10.0.0.0/24
      |      +------+ CORE +-----+      |   +-------
eth0 |      |      |      |     |      |   |
------+ LSR1 |      +------+     | LSR2 +---+
      |      |eth2               |      |   |
      |      +-------------------+      |
      +------+       LINK0       +------+

   all three PCs are running kernel-2.4.19 with a
mpls patch 1.160.

   on lsr1 , i have three ethether net adaptors.

     eth0 is the ingress device
     eth1 has an outgoing label 1
     eth2 has an outgoing label 2

   and two tunnels created by using 'mplsadm -T':

     mpls12 : bind to eth2
     mpls1c : bind to eth1

   and its routing table contains the following
entry:

   10.0.0.0/24 dev mpls12 proto kernel
   core dev mpls1c proto kernel

  now , i want to make a flow with a certain
dst ip address , say , 10.0.0.111, to go throught
this network by balancing the traffic loading
onto eth1 and eth2 on demand.

  e.g. when the direct link between lsr1 and
lsr2 (for convenience we named it LINK0 )are
lighted loaded, the traffic destined to
11.0.0.111 goes out using mpls12 with a label 2.

  when sometimes later, the loading on LINK0
became heavier, i want to shift the traffic
destined to 11.0.0.111 to go out using mpls1c
with label 1.

  can i achieve this ?
  if i can , what should i do then ?

  by the way , i am not using LDP currently.

thanks in advance.

Folke.
