Parameters
vpn-target&<1-8>: Specifies route targets. &<1-8> means that you can specify up to eight route targets.
A route target is a string of 3 to 21 characters in one 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 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.
Description
Route targets are used to control VPN route learning. The MCE adds the specified export targets into
VPN routes advertised a peer. The peer compares the export targets in the received VPN routes against
the local import targets. If a match is found, the peer adds the received routes to the VPN routing table.
Route targets configured in IPv4 VPN view takes precedence over that configured in VPN instance view.
If you configure route targets in both IPv4 VPN view and VPN instance view, those configured in IPv4
VPN view are applied to the IPv4 VPN.
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
# Configure route targets for IPv4 VPN instance vpn2.
<Sysname> system-view
[Sysname] ip vpn-instance vpn2
[Sysname-vpn-instance-vpn2] ipv4-family
[Sysname-vpn-ipv4-vpn2] vpn-target 3:3 export-extcommunity
[Sysname-vpn-ipv4-vpn2] vpn-target 4:4 import-extcommunity
