R3303-HP HSR6800 Routers Layer 3 - IP Routing Command Reference

324
Syntax
filter-policy { acl6-number | ipv6-prefix ipv6-prefix-name } import
undo filter-policy import
Default
RIPng does not filter incoming routing information.
Views
RIPng view
Default command level
2: System level
Parameters
acl6-number: Specifies an IPv6 ACL by its number in the range of 2000 to 3999 to filter incoming routing
information.
ipv6-prefix ipv6-prefix-name: Specifies an IPv6 prefix list by its name, a string of 1 to 19 characters, to
filter incoming routes.
Usage guidelines
To reference 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 rule [ rule-id ] { deny | permit } ipv6
source sour sour-prefix.
• To deny/permit a route with the specified destination and prefix, use rule [ rule-id ] { deny | permit }
ipv6 source sour sour-prefix destination dest dest-prefix.
The source keyword specifies the destination address of a route, and the destination keyword specifies
the prefix of the route. (The prefix must be valid; otherwise, the configuration is ineffective.)
Examples
# Reference IPv6 prefix list Filter1 to filter incoming RIPng updates.
<Sysname> system-view
[Sysname] ripng 100
[Sysname-ripng-100] filter-policy ipv6-prefix Filter1 import
# Configure IPv6 ACL 3000 to permit only route 2001::1/128 to pass, and reference IPv6 ACL 3000 to
filter incoming RIPng updates.
<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
import-route
Use import-route to redistribute routes from another routing protocol.
