Parameters
acl-number: Specifies an ACL by its number in the range of 2000 to 3999 to filter received routes.
prefix-list prefix-list-name: Specifies an IP prefix list by its name, a string of 1 to 63 characters, to filter
received routes.
gateway prefix-list-name: Specifies an IP prefix list by its name, a string of 1 to 63 characters, to filter
routes from the gateway.
interface-type interface-number: Specifies an interface by its type and number.
Usage guidelines
To reference an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL
using one of the following methods:
• To deny/permit a route with the specified destination, use the rule [ rule-id ] { deny | permit } ip
source sour-addr sour-wildcard command
• To deny/permit a route with the specified destination and mask, use the rule [ rule-id ] { deny |
permit } ip source sour-addr sour-wildcard destination dest-addr dest-wildcard command.
The source keyword specifies the destination address of a route and the destination keyword specifies the
subnet mask of the route. The subnet mask must be contiguous. Otherwise, the mask configuration does
not take effect.
Examples
# Use ACL 2000 to filter received RIP routes.
<Sysname> system-view
[Sysname] acl number 2000
[Sysname-acl-basic-2000] rule deny source 192.168.10.0 0.0.0.255
[Sysname-acl-basic-2000] quit
[Sysname] rip 1
