Default level

Parameters
acl6-number: Number of a basic or advanced IPv6 ACL used to filter incoming routes, ranging from
2000 to 3999.
ipv6-prefix-name: Name of an IPv6 prefix list used to filter incoming routes, a string of 1 to 19 characters.
route-policy-name: Name of a routing policy used to filter incoming routes, a string of 1 to 63 characters.
Description
Use the ipv6 filter-policy import command to configure IPv6 IS-IS to filter the received routes.
Use the undo ipv6 filter-policy import command to disable the filtering.
The filtering is disabled by default.
In some cases, only the routing information satisfying certain conditions will be received. You can
configure the filtering conditions using the ipv6 filter-policy command.
NOTE:
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 [
sour-prefix
command to deny/permit a route with the specified destination, or with the rule [
{ deny | permit } ipv6 source
route with the specified destination and prefix. The source keyword specifies the destination address of a
route and the destination keyword specifies the prefix of the route (the prefix must be valid; otherwise, the
configuration is ineffective).
