Parameters
vpn-target&<1-8>: Specifies a space-separated list of up to eight route targets.
A route target is a string of 3 to 21 characters in one of the following formats:
16-bit AS number:32-bit user-defined number. For example, 101:3.
32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.
32-bit AS number:16-bit user-defined number, where the AS number must not be less than 65536. For example, 65536:1.
both: Uses the specified route targets as both import targets and export targets. The both keyword is also used when you do not specify any of the following keywords: both, export-extcommunity, and import-extcommunity.
export-extcommunity: Uses the specified route targets as export targets.
import-extcommunity: Uses the specified route targets as import targets.
all: Removes all route targets.
Usage guidelines
MPLS L3VPN uses route targets to control the advertisement of VPN routing information. A PE adds the configured export targets into the route target attribute of routes advertised to a peer. The peer uses the local import targets to match the route targets of received routes. If a match is found, the peer adds the routes to the routing table of the VPN instance.
Route targets configured in VPN instance view apply to both the IPv4 VPN and the IPv6 VPN. Route targets configured in IPv4 VPN view apply only to the IPv4 VPN. Route targets configured in IPv6 VPN view apply only to the IPv6 VPN.
IPv4 VPN prefers the route targets configured in IPv4 VPN view over those configured in VPN instance view.
IPv6 VPN prefers the route targets configured in IPv6 VPN view over those configured in VPN instance view.
Examples
# Configure route targets for VPN instance vpn1.
<Sysname> system-view [Sysname] ip vpn-instance vpn1 [Sysname-vpn-instance-vpn1] vpn-target 3:3 export-extcommunity [Sysname-vpn-instance-vpn1] vpn-target 4:4 import-extcommunity [Sysname-vpn-instance-vpn1] vpn-target 5:5 both
