1. These are used for filtering BGP routing updates, so
That certain path policy is applied.
2. Prefix lists put less load on the processor compared to
Access lists.
3. Prefix lists are easier to configure and implement.
4. Prefix lists are read one line at a time.
5. There is an implicit deny all at the bottom of the Prefix
List. However, if the prefix list is empty, there will be an implicit permit any.
6. The statement with the smallest sequence numbers is read first.
7. Sequence values are generated in increments of 5. The first sequence value generated in a prefix list would be 5, then 10, then 15,
And so on.
