Default level

Parameters
acl-number: Specifies the number of an ACL that is used to filter routes calculated from received
LSPs, ranging from 2000 to 3999. For ACL configuration information, see ACL and QoS Command
Reference.
ip-prefix ip-prefix-name: Specifies the name of an IP prefix list that is used to filter routes calculated
from received LSPs, a case-sensitive string of 1 to 19 characters. For IP prefix list configuration
information, see
route-policy route-policy-name: Specifies the name of a routing policy that is used to filter routes
calculated from received LSPs, a case-sensitive string of 1 to 63 characters. For routing policy
configuration information, see
Description
Use filter-policy import to configure IS-IS to filter routes calculated from received LSPs.
Use undo filter-policy import to disable IS-IS from filtering routes calculated from received LSPs.
IS-IS does not filter routes calculated from received LSPs by default.
If you want to reference an advanced ACL (with a number from 3000 to 3999) in the command or in
the routing policy, the ACL should be configured with the rule [ rule-id ] { deny | permit } ip source
sour-addr sour-wildcard command to deny/permit a route with the specified destination, or with the
rule [ rule-id ] { deny | permit } ip source sour-addr sour-wildcard destination dest-addr
dest-wildcard command to deny/permit a route with the specified destination and mask. 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).
