display ip routing-table acl
Use display ip routing-table acl to display information about routes permitted by a specific basic ACL.
Syntax
display ip routing-table [ vpn-instance vpn-instance-name ]acl acl-number [ verbose ]
Views
Any view
Predefined user roles
network-admin
network-operator
Parameters
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string
of 1 to 31 characters. Without this option, the command displays routing information for the public
network.
acl-number: Specifies a basic ACL by its number in the range of 2000 to 2999.
verbose: Displays detailed information about all routes permitted by the basic ACL. Without this keyword,
the command displays only brief information about active routes permitted by the basic ACL.
Usage guidelines
If the specified ACL does not exist or has no rules configured, the command displays information about
all routes.
Examples
# Define basic ACL 2000 and set the route filtering rules.
<Sysname> system-view
[Sysname] acl number 2000
[Sysname-acl-basic-2000] rule permit source 192.168.1.0 0.0.0.255
[Sysname-acl-basic-2000] rule deny source any
# Display brief information about active routes permitted by basic ACL 2000.

display ip routing-table ip-address
Use display ip routing-table ip-address to display information about routes to a specific destination
address.
Use display ip routing-table ip-address1 to ip-address2 to display information about routes to a range of
destination addresses.
Syntax
display ip routing-table [ vpn-instance vpn-instance-name ] ip-address [ mask |mask-length ]
[ longer-match ] [ verbose ]
display ip routing-table [ vpn-instance vpn-instance-name ] ip-address1 to ip-address2 [ verbose ]

Parameters
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string
of 1 to 31 characters. Without this option, the command displays routing information for the public
network.
ip-address: Specifies a destination IP address in dotted decimal notation.
mask: Specifies the IP address mask in dotted decimal notation.
mask-length: Specifies the mask length, an integer in the range of 0 to 32.
longer-match: Displays the route entry with the longest mask.
ip-address1 to ip-address2: Specifies a destination IP address range.
verbose: Displays detailed routing table information, including information about both active and
inactive routes. Without this keyword, the command displays brief information about active routes.

Usage guidelines
Executing the command with different parameters yields different outputs:
•display ip routing-table ip-address:
{The system ANDs the entered destination IP address with the subnet mask in each active route
entry.
{The system ANDs the destination IP address in each active route entry with its own subnet mask.
If the two operations yield the same result for an entry, the entry is displayed.
•display ip routing-table ip-address mask:
{The system ANDs the entered destination IP address with the entered subnet mask.
{The system ANDs the destination IP address in each active route entry with the entered subnet
mask.
If the two operations yield the same result for an entry and the entry has a subnet mask less than
or equal to the entered subnet mask, the entry is displayed.
•display ip routing-table ip-address longer-match:
{The system ANDs the entered destination IP address with the subnet mask in each active route
entry.
{The system ANDs the destination IP address in each active route entry with its own subnet mask.
If the two operations yield the same result for multiple entries, the one with longest mask length is
displayed.
•display ip routing-table ip-address mask longer-match:
{The system ANDs the entered destination IP address with the entered subnet mask.
{The system ANDs the destination IP address in each active route entry with the entered subnet
mask.
If the two operations yield the same result for multiple entries and the entries have a mask less than
or equal to the entered subnet mask, the one with the longest mask length is displayed.
•display ip routing-table ip-address1 to ip-address2:
The system displays active route entries with destinations in the range of ip-address1/32 to
ip-address2/32.

Parameters
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string
of 1 to 31 characters. Without this option, the command displays routing information for the public
network.
prefix-list-name: Specifies an IP prefix list by its name, a case-sensitive string of 1 to 63 characters.
