Parameters

Parameter	Description	Value
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.
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.
network	Specifies an IPv4 network address.	The value is in dotted decimal notation.

mask	Specifies the mask of an IPv4 address.	The value is in dotted decimal notation.
longer-prefixes	Matches according to the mask longer than the specified length.	-
community-filter basic-community-filter-number	Specifies the number of a basic community filter.	The value is an integer ranging from 1 to 99.
community-filter community-filter-name	Specifies the name of the community filter.	The value is a string of 1 to 51 case-sensitive characters. The string cannot be all digits.
community-filter advanced-community-filter-number	Specifies the number of an advanced community filter.	The value is an integer ranging from 100 to 199.
whole-match	Indicates exact matching.	-
community community-number	Specify community number.	The value is an integer ranging from 0 to 4294967295.
community aa:nn	Specify aa<0-65535>:nn <0-65535>.	The value is a string of 1 to 11 case-sensitive characters, spaces not supported.
internet	Displays the BGP public network routes carrying the internet community attribute.	-
no-advertise	Displays the BGP public network routes carrying the No-Advertise community attribute.	-
no-export	Displays the BGP public network routes carrying the No-Export community attribute.	-
no-export-subconfed	Displays the BGP public network routes carrying the No-Export-Subconfed community attribute.	-
large-community aa:bb:cc	Specifies a value of the Large-Community attribute.	The value is a string of 5 to 32 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.
large-community-filter large-community-filter-name	Specifies the name of a Large-Community filter.	The value is a string of 1 to 51 case-sensitive characters, spaces not supported.
