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

323
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 advertised
routing information.
ipv6-prefix ipv6-prefix-name: Specifies an IPv6 prefix list by its name, a string of 1 to 19 characters, to
filter routing information.
protocol: Filters routes redistributed from a routing protocol, including bgp4+, direct, isisv6, ospfv3,
ripng, and static.
process-id: Specifies the process ID of the specified routing protocol, in the range of 1 to 65535. This
argument is available only when the routing protocol is ripng, ospfv3, or isisv6.
Usage guidelines
With the protocol argument specified, only routing information redistributed from the specified routing
protocol will be filtered. Otherwise, all outgoing routing information will be filtered.
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
# Use IPv6 prefix list Filter 2 to filter advertised RIPng updates.
<Sysname> system-view
[Sysname] ripng 100
[Sysname-ripng-100] filter-policy ipv6-prefix Filter2 export
# Configure IPv6 ACL 3000 to permit only route 2001::1/128 to pass, and reference IPv6 ACL 3000 to
filter advertised 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 export
filter-policy import (RIPng view)
Use filter-policy import to define an inbound route filtering policy. Only routes that match the filtering
policy can be received.
Use undo filter-policy import to disable inbound route filtering.
