Parameters

Parameter	Description	Value
all	Displays all the BGP routes of MDT.	-
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.
as-path-filter	Displays the routes that match a specified filter.	-
as-path-filter-number	Specifies the number of the matched AS_Path filter.	It is an integer that ranges from 1 to 256.
as-path-filter-name	Specifies the name of the matching AS_Path filter.	The value is a string of 1 to 51 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.
regular-expression as-regular-expression	Specifies the regular expression that AS_Path matched.	The value is a string of 1 to 80 characters.
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.
peer ipv4-address	Displays the routes of the specified BGP peer.	The value is in dotted decimal notation.
advertised-routes	Displays the routes advertised to a specified peer.	-
received-routes	Displays the routes received from the specified peer.	-
active	Displays the active routes received from the specified peer.	-
