Configuring Route Attributes For A Vpn Instance - HP 10500 SERIES Configuration Manual

Step
2. Enter interface view.
3. Associate a VPN instance
with the interface.
NOTE:
The ip binding vpn-instance command clears the IPv6 address of the interface on which it is configured.
Be sure to re-configure an IPv6 address for the interface after configuring the command.

Configuring route attributes for a VPN instance

The MCE controls VPN route advertisement as follows:
When a VPN route learned from a VPN site gets redistributed into BGP, BGP associates it with a
•
VPN target extended community attribute list, which is usually the export target attribute of the VPN
instance associated with the VPN site.
The VPN instance determines which routes it can accept and redistribute according to the
•
import-extcommunity in the VPN target.
• The VPN instance determines how to change the VPN targets attributes for routes to be advertised
according to the export-extcommunity in the VPN target.
IMPORTANT:
Create a routing policy before associating it with a VPN instance. Otherwise, the device cannot filter the
routes to be received and advertised.
To configure route related attributes for a VPN instance:
Step
1. Enter system view.
2. Enter VPN instance view.
3. Enter IPv6 VPN view.
4. Configure VPN targets.
5. Set the maximum number of
routes supported.
6. Apply an import routing
policy.
