Hi,
I have configured static routes between two routers. I have 4 links between the routers & have traffic routed.
The interface IP address :
Router -1:
Serial 0/0/0 - 192.168.248.1 255.255.255.252
Serial0/1/0 - 192.168.248.5 255.255.255.252
Serial0/2/0:0 - 192.168.248.9 255.255.255.252
Serial0/2/1:0 - 192.168.248.13 255.255.255.252
There's static routes configured for networks as shown below:
ip route 192.168.130.0 255.255.255.0 192.168.248.2
ip route 192.168.130.0 255.255.255.0 192.168.248.6
ip route 192.168.130.0 255.255.255.0 192.168.248.10
ip route 192.168.130.0 255.255.255.0 192.168.248.14
Now, when I check the traffic, I see there is one way traffic issue. I see all the traffic going via 192.168.248.14 interface only.
& on the other end as well, all traffic is traversing 192.168.248.5 interface one way.
I do not see traffic on the other two links at all.
Can you please assit in this? I want only static routing on my routers & want equal distribution of traffic on all the four links.

Can you post a "sh ip route" from the router.

Hello Deepa,
you need to have multiple traffic flows to see load balancing in effect.
load balancing is based on exor of
source ip address exor dest ip address exor hash seed
so if all your traffic belongs to a single flow (same ip source, same ip dest) you will see only one link used in each direction
Hope to help
