• To deny/permit a route with the specified destination and prefix, use rule [ rule-id ] { deny | permit }
ipv6 source sour sour-prefix destination dest dest-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 contiguous. Otherwise, the configuration does not take effect.
Using the filter-policy export command filters only routes redistributed by the import-route command. If
the import-route command is not configured to redistribute routes from other protocols and other OSPFv3
processes, the filter-policy export command does not take effect.
Examples
# Use IPv6 prefix list abc to filter redistributed routes.
<Sysname> system-view
[Sysname] ipv6 prefix-list abc permit 2002:1:: 64
[Sysname] ospfv3
[Sysname-ospfv3-1] filter-policy prefix-list abc export
# Configure IPv6 ACL 3000 to permit only route 2001::1/128. Use ACL 3000 to filter redistributed
routes.
<Sysname> system-view
[Sysname] acl ipv6 number 3000
[Sysname-acl6-adv-3000] rule 10 permit ipv6 source 2001::1 128 destination
ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff 128
[Sysname-acl6-adv-3000] rule 100 deny ipv6
[Sysname-acl6-adv-3000] quit
[Sysname] ospfv3
[Sysname-ospfv3-1] filter-policy 3000 export
