display bgp mdt routing-table (different-origin-as and cidr)

Function

The display bgp mdt routing-table different-origin-as command displays BGP MDT routes that have the same destination address but different source AS numbers.

The display bgp mdt routing-table cidr command displays classless inter-domain routing (CIDR) information about BGP MDT routes.

Format

display bgp mdt { all | vpn-instance vpn-instance-name | route-distinguisher route-distinguisher } routing-table different-origin-as

display bgp mdt { all | vpn-instance vpn-instance-name | route-distinguisher route-distinguisher } routing-table cidr

Parameters

Parameter	Description	Value
all	Displays all the BGP routes of MDT.	-
vpn-instance vpn-instance-name	Displays the BGP routing information of the specified VPN instance.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string.
route-distinguisher route-distinguisher	Displays BGP routing information of the specified Route Distinguisher (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. 4-byte AS number in dotted notation is in the format of x.y, wherex 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.

Parameter

Description

Value

all

Displays all the BGP routes of MDT.

vpn-instance vpn-instance-name

Displays the BGP routing information of the specified VPN instance.

The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string.

route-distinguisher route-distinguisher

Displays BGP routing information of the specified Route Distinguisher (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.
4-byte AS number in dotted notation is in the format of x.y, wherex 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.
