Use the
undo filter-policy
export
command to disable the outbound route filtering.
By default, RIPng does not filter any outbound routing information.
Note that:
z
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.
z
If you want to reference an advanced ACL (with a number from 3000 to 3999) in the
command, the ACL should be configured with the
rule
[
rule-id
] {
deny
|
permit
}
ipv6
source
sour sour-prefix
command to deny/permit a route with the specified destination, or
with the
rule
[
rule-id
] {
deny
|
permit
}
ipv6 source
sour sour-prefix
destination
dest
dest-prefix
command to deny/permit a route with the specified destination and prefix. The
source
keyword specifies the destination address of a route while the
destination
keyword
specifies the prefix of the route (the prefix must be valid; otherwise, the configuration is
ineffective).
Examples
# Use IPv6 prefix list
Filter 2
to filter advertised RIPng updates.

[Sysname] ripng 100
[Sysname-ripng-100] filter-policy ipv6-prefix Filter2 export
# Configure ACL6 3000 to permit only route 2001::1/128 to pass, and reference ACL6 3000 to
filter advertised RIPng updates.
