OSPF Sham Links - Problem

Dear All,

Wwe have recently provided one odd customer with OSPF sham links and customer has asked to provide load-sharing on both the service providers.

All CE routers are configured as AREA-0.

The fallback onto SP-2 is happening but whenever we apply the "ip ospf cost 1" on both the interfaces, it does not load-share the uplink/downlink traffic on both the service providers.

We have changed the cost on PE -to-PE sham link but to no avail.

we haved asked customerf to contact their SP-1 to apply the sham-link cost to 1 sothat cust requirement can be achieved.

Please share the exact reason and workaround.
