Default Level
2: System level
Parameters
acl6-number: Specifies the number of an ACL to filter advertised routing information, in the range of
2000 to 3999.
ipv6-prefix ipv6-prefix-name: Specifies the name of an IPv6 prefix list used to filter routing information,
a string of 1 to 19 characters.
protocol: Filters routes redistributed from a routing protocol, currently including bgp4+, direct, isisv6,
ospfv3, ripng, and static.
process-id: Process number of the specified routing protocol, in the range of 1 to 65535. This argument
is available only when the routing protocol is rip, ospf, or isis.
Description
Use the filter-policy export command to define an outbound route filtering policy. Only routes passing
the filter can be advertised in the update messages.
Use the undo filter-policy export command to restore the default.
By default, RIPng does not filter any outbound routing information.
With the protocol argument specified, only routing information redistributed from the specified routing
protocol will be filtered. Otherwise, all outgoing routing information will be filtered.
Examples
# Use IPv6 prefix list Filter 2 to filter advertised RIPng updates.
