R2511-HP MSR Router Series Layer 3 - IP Routing Command Reference(V5)

337
protocol: Filters routes redistributed from a routing protocol, including bgp4+, direct, isisv6, ospfv3,
ripng, and static.
process-id: Specifies the process number 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, RIPng filters only routes redistributed from the specified routing
protocol. Otherwise, RIPng filters all redistributed routes.
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 redistributed RIPng updates.
<Sysname> system-view
[Sysname] ripng 100
[Sysname-ripng-100] filter-policy ipv6-prefix Filter2 export
# Configure ACL6 3000 to permit only route 2001::1/128. Use ACL6 3000 to filter redistributed 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 configure RIPng to filter received routes. Only routes that match the filtering
policy can be received.
Use undo filter-policy import to disable received route filtering.
Syntax
filter-policy { acl6-number | ipv6-prefix ipv6-prefix-name } import
undo filter-policy import
Default
RIPng does not filter incoming routing information.
