OSPF load balancing

[gsantini]

I have 3 routers in a classic triangle configuration connected with 1 STM1 each one. 2 routers have 2 STM1 between them. At the point of view of the un router that have 3 STM1, I need to load balancing between all interfaces.

Hola,

OSPF supports only equal cost load balancing. You can use the interface command 'ip opsf cost' and configure the same value on all participating interfaces, forcing the router(s) to perform load balancing.

Hi,

Anothet thing that you can do if you do not want to manipulate the cost is to use the bandwidth on the interfaces . Make sure you configure the same bandwidth on all the intercaes hence same cost so OSPF will perorm load balancing.

thanks

Just to clarify a little bit, you have to take care the the sum of the cost of the outgoing interfaces of the path from origin router to the destination router.

It seems that you won´t be able to load balance for all the routers, just for a couple of them.
