Parameters

Parameter Description Value

all

Displays all BGP VPNv4 routes.

-

route-distinguisher route-distinguisher

Displays the BGP routes with the specified RD.

The RD formats are divided into the following types:
  • 2-byte AS number:4-byte user-defined number, for example, 101:3. An AS number ranges from 0 to 65535. A user-defined number ranges from 0 to 4294967295. The AS number and the user-defined number cannot be 0s at the same time. That is, an RD cannot be 0:0.

  • Integral 4-byte AS number:2-byte user-defined number, for example, 65537:3. An AS number ranges from 65536 to 4294967295. A user-defined number ranges from 0 to 65535. The AS number and user-defined number cannot be both 0s. That is, an RD cannot be 0:0.

  • 4-byte AS number in dotted notation:2-byte user-defined number, for example, 0.0:3 or 0.1:0. A 4-byte AS number in dotted notation is in the format of x.y, where x and y are integers that range from 0 to 65535 and from 0 to 65535, respectively. A user-defined number ranges from 0 to 65535. The AS number and user-defined number cannot be both 0s. That is, an RD cannot be 0.0:0.

  • IPv4-address:2-byte user-defined number, for example, 192.168.122.15:1. An IP address ranges from 0.0.0.0 to 255.255.255.255. A user-defined number ranges from 0 to 65535.

vpn-instance vpn-instance-name

Displays the BGP routes of a specified VPN instance.

The value must be an existing VPN instance name.

as-path-filter

Displays the routes that match the specified filter.

-

as-path-filter-number

Specifies the number of the matching AS-Path filter.

The value is an integer that ranges from 1 to 256.

as-path-filter-name

Specifies the name of the matching AS-Path filter.

The name is a string of 1 to 51 case-sensitive characters without spaces. The string cannot be all numerals. When double quotation marks are used around the string, spaces are allowed in the string.

cidr

Displays CIDR information.

-

different-origin-as

Displays the routes that have the same destination address but different source AS numbers.

-

regular-expression as-regular-expression

Specifies the regular expression used to match the AS_Path information.

The value is a string of 1 to 80 characters.

verbose

Displays detailed information about BGP VPNv4 routes.

-

ipv4-address

Specifies the destination address.

-

mask

Specifies a mask in dotted decimal notation.

The value is in dotted decimal notation.

mask-length

Specifies the mask length.

The value is an integer that ranges from 0 to 32.

peer ipv4-address

Displays routes of a specified peer.

-

advertised-routes

Displays the routes advertised to a specified peer.

-

network

Specifies the IPv4 network address.

The value is in dotted decimal notation.

longer-prefixes

Matches any route whose prefix mask is longer than the specified length.

-

received-routes

Displays the routes received from a specified peer.

-

active

Displays the active routes received from a specified peer.

-

original-attributes

Displays the original attributes of a BGP route from a specified BGP peer before the route is filtered by the local import policy. To display such attributes, the peer keep-all-routes command must have been run.

-

community-filter

Displays the routes that match a specified BGP community filter.

-

community-filter-name

Specifies the name of a community filter.

The value is a string of 1 to 51 case-sensitive characters. The string cannot be all digits.

basic-community-filter-number

Specifies the number of a basic community filter.

The value is an integer that ranges from 1 to 99.

whole-match

Indicates exact matching.

-

advanced-community-filter-number

Specifies the number of an advanced community filter.

The value is an integer that ranges from 100 to 199.

community

Displays the routes carrying the specified BGP community attribute in the routing table.

-

community-number

Specifies the number of a community.

-

aa:nn

Specifies the community number. A maximum of 29 community numbers can be set.

Both aa and nn are integers ranging from 0 to 65535.

internet

Displays the matching routes that can be sent to any peer.

-

no-advertise

Displays the BGP routes carrying the No-Advertise community attribute.

-

no-export

Displays the BGP routes carrying the No-Export community attribute.

-

no-export-subconfed

Displays the BGP routes carrying the No-Export-Subconfed community attribute.

-

accepted-routes

Displays the routes that are received from a neighbor and accepted by a routing policy.

-

time-range start-time end-time

Displays information about BGP VPNv4 routes that have undergone status flapping during the specified period. For example, when start-time is set to 0d0h5m0s and end-time is set to 0d0h10m0s, information about all BGP VPNv4 routes whose lifetime ranges from 5 to 10 minutes is displayed.

In the values of start-time and end-time, d ranges from 0 to 10000, h ranges from 0 to 23, m ranges from 0 to 59, and s ranges from 0 to 59.

All views

Default Level

1: Monitoring level

Usage Guidelines

You can specify different parameters to view the specific routing information.

When BGP routing table is displayed, if the length of the destination address mask of an IPv4 route is the same as that of its natural mask, the mask length is not displayed.

You can run the display bgp vpnv4 { all | vpn-instance vpn-instance-name } routing-table time-range start-time end-time command to view BGP VPNv4 routes that flap within the specified time period. For example, if service traffic is abnormal or CPU usage of the device remains high within a certain time period, you can run this command to check whether route flapping occurs within the specified time period. The faulty route can be viewed in the command output, facilitating fault location.

origin incomplete

Well-known mandatory property. This property defines the origin of a path and records how a route turns to a BGP route. The property has the following three values:
  • IGP: The priority of this value is the highest. The origin property of the routes that are added to the BGP routing table by using the network (BGP) command is IGP.

  • EGP: The priority of this value is second to that of IGP. The origin property of the routes imported from EGP is EGP.

  • Incomplete: The priority of this value is the lowest. The value indicates the origin of a route is unknown. The origin property of the routes that are added to the BGP routing table by using the import-route (BGP) command is Incomplete.

MED

Multi-Exit discriminator of route.

localpref

Local priority.

pref-val

Value preferred by the protocol.

valid

The BGP route is a valid route.

internal

The BGP route is an internal route.

best

The BGP route is an optimal route.

select

The BGP route is a preferred route.

pre 255

The priority of the BGP route is 255.

invalid for tunnel unreachable

Reason why a route is invalid:

  • invalid for route-policy not pass: The route does not match the route-policy.

  • invalid for supernet route: The route is a supernet route.

  • invalid for IP unreachable: The route fails to be iterated to another route.

  • invalid for supernet route not advertise: No supernet routes are advertised.

  • invalid for supernet label route not advertise: No supernet labeled routes are advertised.

  • invalid for next-hop unreachable: The next-hop IP address is unreachable.

  • invalid for tunnel unreachable: The route fails to be iterated to a tunnel.

Not advertised to any peer yet

The BGP route has not been advertised to any peer yet.
