[j-nsp] Configuring Per-Packet Load Balancing

[Mesut Mutlu]

Hi,

Thanks for help again.

I think I should have explained my topology for which
I want to make load-balance per-packet configuration
before.

Our customer have three seperate links from his router
to my router.(On both side there is only one router.)
There is BGP running over these links using loopback
address on both side and three static routes are
defined to customer side loopback address.
The customer is advertising 4 routes (listed below in
configuration beginning with 192.168.) through BGP to
me. I just want to load-balance packets which are
going to these routes. 
I made a configuration with your assistance which is
below:

mes at Jun> show configuration policy-options
policy-statement equal-cost

term load_balance{
    from {
        route-filter 192.168.205.0/24 exact 
        route-filter 192.168.206.0/24 exact 
        route-filter 192.168.207.0/24 exact 
        route-filter 192.168.204.0/22 exact     
    then {
        load-balance per-packet;
    }
}
**
mes at Jun> show configuration routing-options
forwarding-table 
   
export equal-cost;

******
Forwarding Table of my router to loopback address of
my customer (172.16.1.2)  is seen as below:

mes at Jun>  show route forwarding-table matching
172.16.1.2
 
Routing table: inet
Internet:
Destination        Type RtRef Next hop           Type
Index NhRef Netif
172.16.1.2/32 user     1                    ulst   283
    3
                              10.0.0.140     ucst  
822     2 at-2/2/0.1  
                              10.0.0.136     ucst  
782     2 at-2/2/0.2  
                              10.0.0.128     ucst  
845     2 at-2/2/0.3  

Routing table: __juniper_private1__.inet
Internet:
mes at Jun> show configuration forwarding-options 
 
hash-key {
    family inet {
        layer-3;
        layer-4;
    }
}

******
When I monitor the traffic passed to customer on each
interface there is unequality among amount of packets
.

Could you please remark errors on this configuration
and explain what would right configuration look like.

Have a nice work.
