Hello Zaman
The tie breakers will be checked based on the number found after the index keyword. That number is essentially a priority index. The lower the number, the more important the attribute. So the order the attributes will be checked will be in ascending order of the index number.
Each tie breaker will eliminate paths with specific attributes. The attributes indicated in your example eliminate the following paths:
Primary-path—Eliminates candidates that are not ECMPs
Interface-disjoint—Eliminates candidates sharing the same interface with the protected path
Lowest-metric — Eliminates the path with the lowest metric
Linecard-disjoint—Eliminates candidates sharing the same linecard with the protected path
Broadcast-interface-disjoint — Eliminates candidates sharing the same interface and the broadcast network connected to it
You can find more info at this Cisco documentation.
I hope this has been helpful!
