Usage guidelines
To use an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL in one
of the following ways:
•
To deny/permit a route with the specified destination, use the
rule
[
rule-id
] {
deny
|
permit
}
ip
source
sour-addr sour-wildcard
command.
•
To deny/permit a route with the specified destination and prefix, use the
rule
[
rule-id
] {
deny
|
permit
}
ip source
sour-addr sour-wildcard
destination
dest-addr dest-wildcard
command.
The
source
keyword specifies the destination address of a route and the
destination
keyword specifies the
prefix of the route. The subnet mask must be contiguous. Otherwise, the configuration does not take
effect.
Examples
# Reference IPv6 prefix list to filter received RIPng updates.
<Sysname> system-view
[Sysname] ipv6 prefix-list abc index 10 permit 100:1:: 32
[Sysname] ripng 100
[Sysname-ripng-100] filter-policy prefix-list abc import
# Configure IPv6 ACL 3000 to permit only route 2001::1/128 to pass. Use IPv6 ACL 3000 to filter
received 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] ripng 100
[Sysname-ripng-100] filter-policy 3000 import
