Default command level
2: System level
Parameters
acl-number: Specifies an ACL by its number in the range of 2000 to 3999 to filter routes calculated from
received LSPs. For ACL configuration information, see ACL and QoS Command Reference.
ip-prefix ip-prefix-name: Specifies an IPv4 prefix list by its name, a case-sensitive string of 1 to 19
characters, to filter routes calculated from received LSPs. For IP prefix list configuration information, see
"Routing policy configuration commands."
route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63
characters, to filter routes calculated from received LSPs. For routing policy configuration information, see
"Routing policy configuration commands."
Usage guidelines
To reference an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL
in one of the following ways:
• 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 valid; otherwise, the configuration is ineffective.)
Examples
# Reference ACL 2000 to filter routes calculated from received LSPs.
<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] isis 1
[Sysname-isis-1] filter-policy 2000 import
# Configure ACL 3000 to permit only route 113.0.0.0/16 to pass, and reference ACL 3000 to filter
routes calculated from received LSPs.
<Sysname> system-view
[Sysname] acl number 3000
[Sysname-acl-adv-3000] rule 10 permit ip source 113.0.0.0 0 destination 255.255.0.0 0
