ospf routing

Hi we have one cisco 3800 series router and we have two 34 Mbps links configured on that we want to do the load balancing using the both links in parallel. Here we have used OSPF routing protocol. If you have any suggestion pls let me know.

Re: ospf routing

OSPF will do equal cost load balancing by default. so if you want to load balance between the two 34 meg links, simply make their cost equal. use the 'ip ospf cost' command in interface config mode.

Rakesh,

If you want to split traffic among your lines according to the type of traffic, you will need to use Policy Based Routing (PBR). The OSPF will not help you here.

Are you familiar with the PBR?

Re: ospf routing

Hi Rakesh,

Please try to be more specific. Those two 34 Mbps links are uplinks to your ISP? Do you communicate with your ISP using OSPF? Do both these links provide connectivity to the same set of IP networks?

Best regards,

Peter
