65535. An item with a smaller index number is matched first. If you do not specify this option, the
index number starts from 10 and increments by 10 for each of the consecutive prefix list items.
deny : Specifies the deny mode. If a route matches the item, the route is denied without being
compared with the next item. If a route does not match the item, the route is compared with the next
item.
: Specifies the permit mode. If a route matches the item, it passes the IPv4 prefix list. If a
permit
route does not match the item, the route is compared with the next item.

Usage guidelines
An IPv4 prefix list is used to filter IPv4 addresses. It can contain multiple items, each of which
specifies a range of IPv4 prefixes. The relation between the items is logical OR. If an item is passed,
the IPv4 prefix list is passed. If no item is passed, the IP prefix list cannot be passed.
If both the
ip-address
route will be matched.
To match all routes, use 0.0.0.0 0
Examples
# Configure IP prefix list p1 to permit routes destined for network 10.0.0.0/8 and with mask length 17
or 18.

[Sysname] ip prefix-list p1 permit 10.0.0.0 8 greater-equal 17 less-equal 18
