Parameters

Parameter	Description	Value
vpnv4	Indicates the VPNv4 address family.	-
vpn-instance vpn-instance-name	Specifies a VPN instance name.	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.
as-path-filter as-path-filter-name	Specifies an AS_Path filter name (a string of 1 to 51 characters, which cannot contain only digits.).	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.
as-path-filter as-path-filter-number	Specifies an AS_Path filter index.	The value is an integer ranging from 1 to 256.
regular-expression as-regular-expression	Displays the routes that match the regular expression.	The value is a string of 1 to 80 characters.
ipv4-address	Specifies an IPv4 network address.	The value is in dotted decimal notation.
mask	Specifies an IPv4 network mask.	The value is in dotted decimal notation.
mask-length	Specifies a length of an IP address mask.	The value is an integer ranging from 0 to 32.
longer-match	Allows longer prefix match.	-
labeled	Specifies the labeled-unicast address family.	-
vpnv6	Indicates the VPNv6 address family.	-
ipv6-address	Specifies an IPv6 network address.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
prefix-length	Specifies an IPv6 network prefix length.	The value is an integer that ranges from 0 to 128.
all	Displays all information on VPNv6 and IPv6 VPN instances.	-
route-distinguisher route-distinguisher	Specifies an RD of a remote route.	The value is a string of 3 to 21 case-sensitive characters, spaces not supported.
instance instance-name	Specifies a BGP multi-instance name.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported.
