ipv6-prefix-name
: Specifies the name of an IPv6 prefix list used to match against the destination of
routing information. The name is a string of 1 to 19 characters.
protocol
: Filters routes redistributed from the routing protocol. It can be
direct
,
isisv6
,
ospfv3
,
ripng
,
or
static
at present. If no protocol is specified, all routes will be filtered when advertised.
process-id
: Process ID of the routing protocol, in the range 1 to 65535. It is available only when the
protocol is
isisv6
,
ospfv3
or
ripng
.
Description
Use the
filter-policy
export
command to filter outbound routes using a specified filter.
Use the
undo filter-policy export
command to cancel filtering outbound routes.
By default, no outbound routing information is filtered.
If a protocol
is specified, only routes redistributed from the specified protocol are filtered. If no protocol
is specified, all redistributed routes will be filtered.
Note that 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).
