Default Level
2: System level
Parameters
acl6-number
: Number of an IPv6 ACL used to match against the destination address field of routing
information, ranging from 2000 to 3999.
ipv6-prefix-name
: Name of an IPv6 prefix list used to match against the destination address field of
routing information, a string of 1 to 19 characters.
Description
Use the
filter-policy import
command to filter inbound routing information using a specified filter.
Use the
undo filter-policy import
command to cancel filtering inbound routing information.
By default, no inbound routing information is 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).
