Parameters

Parameter	Description	Value
all	Displays BGP VPNv4 routes and BGP routes of VPN instances.	-
vpn-instance vpn-instance-name	Displays about the BGP routes of a 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.
community communityNum	Specify community number.	The value is an integer ranging from 0 to 4294967295.
community strCommunityNum	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 routes carrying the internet community attribute.	-
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.	-
whole-match	Indicates exact match with specified communities.	-
whole-match	Indicates exact match with specified large communities.	-
extcommunity	Displays information about BGP routes with a specified extended community attribute.	-
rt	Displays information about BGP routes with the route target (RT) extended community attribute.	-
soo	Displays information about BGP routes with the source of origin (SoO) extended community attribute.	-
strExtCommunity	Specifies the excommunity value. IP<X.X.X.X>:NN<0-65535> or AS<0-65535>:NN<0-4294967295> or AS<65536-4294967295>:NN<0-65535> or AS<0-65535>.<0-65535>:NN<0-65535>.	The attribute is a BGP extended community attribute and can be expressed in any of the following formats: 2-byte AS number:4-byte user-defined number, for example, 1:3. The AS number ranges from 0 to 65535, and the user-defined number ranges from 0 to 4294967295. The AS number and user-defined number cannot both be set to 0. Specifically, the value of the SoO attribute cannot be 0:0. IPv4-address:2-byte user-defined number, for example, 192.168.122.15:1. The IP address ranges from 0.0.0.0 to 255.255.255.255, and the user-defined number ranges from 0 to 65535. Integral 4-byte AS number:2-byte user-defined number, for example, 0:3 or 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. Specifically, the value of the SoO attribute 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 ranging from 1 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. Specifically, the value of the SoO attribute cannot be 0.0:0.
match-any	Displays information about BGP routes with any of the specified extended community attributes.	-
large-community largeCommuStr	Specifies a value of the Large-Community attribute.	The value is a string of 5 to 32 case-sensitive characters, spaces not supported.
regular-expression strRegular	Specifies the regular expression used to match the AS_Path information.	The value is a string of 1 to 80 characters.
instance bgpName	Specifies a BGP multi-instance.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.
