display bgp vpn-target routing-table

Function

The display bgp vpn-target routing-table command displays information about routes in the BGP-VPN-Target address family.

Format

display bgp vpn-target routing-table [ peer ipv4-address { advertised-routes | received-routes } ] [ origin-as origin-as-num ] vpn-target

Parameters

Parameter	Description	Value
peer ipv4-address	Specifies an IPv4 address.	The value is in dotted decimal notation.
advertised-routes	Displays information about routes advertised to a specified peer.	-
received-routes	Displays information about the routes received from the specified peer.	-
origin-as origin-as-num	Displays information about routes with the specified origin AS number in the BGP-VPN-Target address family.	The value is an integer ranging from 0 to 4294967295.
vpn-target	Displays information about a specified VPN target.	The format of a VPN target can be as follows: 2-byte AS number:4-byte user-defined number, for example, 1:3. An AS number is an integer ranging from 0 to 65535, and a user-defined number is an integer ranging from 0 to 4294967295. The AS and user-defined numbers cannot be both 0s. This means that a VPN target cannot be 0:0. Integral 4-byte AS number:2-byte user-defined number, for example, 65537:3. An AS number is an integer ranging from 65536 to 4294967295, and a user-defined number is an integer ranging from 0 to 65535. 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 0 to 65535. A user-defined number is an integer ranging from 0 to 65535. The AS and user-defined numbers cannot be both 0s. This means that a VPN target cannot be 0.0:0. 32-bit IP 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, and a user-defined number is an integer ranging from 0 to 65535.
