Configuring route related attributes for a VPN instance
VPN routes are controlled and advertised on a PE using the following process:
When a VPN route learned from a CE gets redistributed into BGP, BGP associates it with a route
•
target extended community attribute list, which is usually the export target attribute of the VPN
instance associated with the CE.
• The VPN instance determines which routes it can accept and redistribute according to the
import-extcommunity in the route target.
The VPN instance determines how to change the route target attributes for routes to be advertised
•
according to the export-extcommunity in the route target.
To configure route related attributes for a VPN instance:
Step
1. Enter system view.
2. Enter VPN instance view or
IPv6 VPN view.
3. Configure route targets.
4. Set the maximum number of
routes supported.

Remarks
N/A
By default, no VPN instance is
associated with an interface.
The ip binding vpn-instance
command clears the IP address of
the interface. Therefore,
re-configure an IP address for the
interface after configuring this
command.
Remarks
N/A
Configurations made in VPN
instance view apply to both IPv4
VPN and IPv6 VPN.
IPv6 VPN prefers the
configurations in IPv6 VPN view
over the configurations in VPN
instance view.
By default, no route targets are
configured.
By default, no route limit is
configured for a VPN instance.
This setting prevents a VPN
instance from storing too many
routes.
