VPN-instance.

By default, the default value is both.

Use the vpn-target command to create ingress and egress route target extended 
community lists for a specified VPN-instance. Execute this command once for each 
target community. Import the received routing information carrying the specific 
VPN-target extended community to all VPN-instances, for which an extended 
community is configured as ingress VPN-target. VPN-target specifies a target VPN 
extended community. The same as RD, an extended community is either 
composed of an ASN and an arbitrary number, or composed of an IP address and 
an arbitrary number.

RD is in either of the following formats:

16-bit ASN (can be 0 here): A custom 32-bit number, for example, 101:3.

32-bit IP address (can be 0.0.0.0 here): A custom 16-bit number, for example, 
192.168.122.15:1.
