A prefix list can have multiple rules. Routes are evaluated against other rules in
sequential order. When a route matches a rule, the deny or permit action occurs and
the route isn’t evaluated against subsequent rules.
Use prefix lists to filter routes based on
prefixes. By defining an order number and IP prefixes, a branch
or a data center ION device can permit or deny routes. The dynamic,
auto-generated prefix list is based on what the ION device advertises. Prefixes
can be split or non-split.
