Parameters
ipv6-acl-number: Specifies an IPv6 ACL by its number in the range of 2000 to 3999 to filter received routes.
prefix-list prefix-list-name: Specifies an IPv6 prefix list by its name, a string of 1 to 63 characters, to filter received routes.
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 } ipv6 source sour sour-prefix command.
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. For the configuration to take effect, specify a contiguous prefix.
Examples
# Use the IPv6 prefix list abc 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 advanced IPv6 ACL 3000 to permit only route 2001::1/128 to pass. Use advanced IPv6 ACL 3000 to filter received routes.
<Sysname> system-view [Sysname] acl ipv6 advanced 3000 [Sysname-acl-ipv6-adv-3000] rule 10 permit ipv6 source 2001::1 128 destination ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff 128 [Sysname-acl-ipv6-adv-3000] rule 100 deny ipv6 [Sysname-acl-ipv6-adv-3000] quit [Sysname] ripng 100 [Sysname-ripng-100] filter-policy 3000 import
