HUAWEI NetEngine80E/40E Router
Configuration Guide - IP Routing
match-network is used to filter routes to a specified IPv6 address and can be configured only
when ipv6-address is 0.0.0.0. For example, the ip ipv6-prefix prefix1 permit :: 96 command
filters all IPv6 routes with mask length 96, while the ip ipv6-prefix prefix1 permit :: 96 match-
network command filters all routes to the IPv6 address range from ::1 to ::FFFF:FFFF.
The range of the prefix length can be specified as prefix-length <= greater-equal-value <= less-
equal-value <= 128. If only greater-equal is specified, the range of the prefix is [greater-equal-
value, 128]; if only less-equal is specified, the range of the prefix is [prefix-length, less-equal-
value].
An IPv6 prefix list is identified by its list name. Each prefix list can include multiple entries.
Each entry can independently specify the matching range in the form of the network prefix and
identify it with an index number. For example, the following shows an IPv6 prefix list named
abcd:

#

ip ipv6-prefix abcd index 10 permit 2001:db8:1:: 64
ip ipv6-prefix abcd index 20 permit 2001:db8:2:: 64
During the matching, the system checks the entries identified by the index numbers in an
ascending order. When a route matches an entry, it does not match other entries.
In NE80E/40E, all unmatched routes are filtered. If all entries are in deny mode, all routes are
filtered. It is recommended that you define a permit :: 0 less-equal 128 after multiple entries
in deny mode, therefore allowing all the other IPv6 routes to pass the IP prefix list.
Step 3 (Optional) Run:
ip ipv6-prefix ipv6-prefix-name description text
The description information of the IPv6 prefix list is displayed.

10.2.4 Checking the Configurations

After an IP prefix list is configured, you can check information about the IP prefix list.
Prerequisites
The IP-Prefix list has been configured.
Procedure
l
l
----End
Example
Run the display ip ip-prefix p1 command. You can view information about the prefix list named
p1.
Issue 02 (2014-09-30)
NOTE
If more than one IP-prefix entry is defined, at least one entry should be in the permit mode.
Run the display ip ip-prefix [ ip-prefix-name ] command to check information about the
IPv4 prefix list.
Run the display ip ipv6-prefix [ ipv6-prefix-name ] command to check information about
the IPv6 prefix list.
