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, use of 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
filter-policy import (OSPFv3 view)
Use
filter-policy import
to configure OSPFv3 to filter routes calculated using received LSAs.
Use
undo filter-policy import
to restore the default.
