To deny/permit a route with the specified destination and prefix, use the
rule
[
rule-id
] {
deny
|
permit
}
ipv6 source
sour sour-prefix
destination
dest dest-prefix
command.
The
source
keyword specifies the destination address of a route and the
destination
keyword specifies the
prefix of the route. The specified prefix must be contiguous. Otherwise, the prefix configuration does not
take effect.
Examples
# Use IPv6 prefix list to filter redistributed 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 export
# Configure IPv6 ACL 3000 to permit only route 2001::1/128 to pass. Use IPv6 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] ripng 100
[Sysname-ripng-100] filter-policy 3000 export
