We are implementing a new WAN and trying to use OSPF Load Balancing between our central site and distribution center. Both circuits use eBGP between the provider's edge routers. These same routers redistribute between eBGP and OSPF. The provider's edge router is a 2821 and our core and distribution center switches are 6509s.
Currently, we are only using the MPLS connection. When both links are active the network replaces the MPLS connection with the MetroE link in the routing table. The redundant/load balancing connection is not established in the routing table. We have manually set the OSPF cost on all interfaces to 1.
When we initially activated the MetroE connection we were not receiving routes from the providers router, they were receiving routes from us. When they started advertising the 1.1.1.x network (eBGP network between their routers) we then received routes from them. It also caused our GRE tunnels to fail. These tunnels are attached to a 2nd 6509 at our central site.
OSPF Load Balancing seemed straight forward. What are we missing?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
