LDP Configuration Commands 759
Description
Use the vpn-target command to create a VPN-target extended community for
VPN-instance.
Use the undo vpn-target command to remove the VPN-target extended
community attributes.
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.
