Parameters
acl6-number: Specifies an IPv6 ACL by its number in the range of 2000 to 3999 to filter redistributed
routes.
prefix-list prefix-list-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63
characters, to filter the redistributed routes.
route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63
characters, to filter redistributed routes.
protocol: Filters routes redistributed from the specified routing protocol, which can be bgp4+, direct,
isisv6, ospfv3, ripng, or static. If no protocol is specified, the command filters routes redistributed from all
routing protocols.
process-id: Specifies a process by its ID in the range of 1 to 65535. This argument is available only when
the protocol is isisv6, ospfv3, or ripng.
Usage guidelines
This command filters routes redistributed by the ipv6 import-route command. Only routes that have not
been filtered can be redistributed.
If no protocol is specified, the command filters routes redistributed from all routing protocols.
If a protocol is specified, the command filters routes redistributed from the specified routing protocol.
To reference an advanced ACL (with a number from 3000 to 3999) in the command or in the routing
policy, 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 } ipv6
source sour sour-prefix command.
• To deny/permit a route with the specified destination and prefix, use the rule [ rule-id ] { deny |
permit } ipv6 source sour sour-prefix destination dest dest-prefix command.
