Hi,

 

Please check below links

 

When there are multiple routes available to the same network with different route types, routers use this order of preference (from highest to lowest):

1. Intra-area routes.  (LSA1 and 2)

2. Inter-area routes.  (LSA3)

3. External Type-1 routes. (LSA5 Type-1)

4. External Type-2 routes. (LSA5 Type-2)
