OSPF sham-link cost
An OSPF sham-link will have a default cost of 1 ensuring that it is chosen as the best path over alternative possible paths. The cost of the sham link can be modified using a command similar to the following:
PE1(config-router)#area 0 sham-link 18.104.22.168 22.214.171.124 cost 10
The cost configured affects only outbound traffic, thus it should be configured the same on both ends of the sham link.
